Comments are a bit outdated.

Helm Costs 13005 honor points and 30 Alterac valley marks
Chestpiece Costs 13770 honor points and 30 arathi basin marks
Shoulderguards Costs 8415 honor points and 20 arathi basin marks
Boots Costs 8415 honor points and 20 arathi basin marks
Gloves cost 8415 honor points and 20 alterac valley marks
Leggings cost 13005 honor points and 30 warsong gulch marks

so the full set is;
65025 honor points, 50 Alterac valley marks, 70 arathi basin marks, and 30 warsong gulch marks.

By far the best looking armor set in the game, I still throw mine on every once in a while for fun. In the WoTLK beta realms, this armor is still available for purchase, and some of the elite NPC's and one peticular city boss wears this armor. I'm glad Blizzard kept this armor set around.

One thing I have noticed is the bonus armour on this set, despite it being a PvP set designed for a dps role. This shows that warrior used to have a much greater amount of suvivability back in Pre-BC - the melee guy that could take a real punch (or at least thats what Blizzard intended) compared to the other classes. I don't know what happened to this theory but I wish Blizzard had stuck to it, just take a look at Warrior suvivability at Level 80, I'm not saying bonus armor would solve it but it just shows how the recent expansion packs have changed the game so much.

On another note. I would like to agree with Shockna on this one. This is still the most awesome looking PvP set for warriors avaliable, I, amoungst others I know have collected this set at a high level even when it's stats have become obsolete purely for it's looks and what they stand for; the might of the Alliance.

It would be very interesting to get a pre bc version of wow and see how different talents, skills and gear worked. If you could go back in time, so to say and get all this gear with the Arcanite Reaper you'd be the scourge of anybody standing in your way.

I wish Blizzard would use the model for this set in the upcoming expansion, as this is, as stated above, one of the coolest looking sets in the warrior set catalogue. Since Blizzard is reinventing Azeroth, it could be logical that they reinvented the 60-PVP sets.

New cost with the marks getting removed in the upcomming patch

Shoulders, Boots and Gloves: 9000 Honor each.
Leggings, Helmet and Chest: 15000 Honor each.

Currently only obtainable after reaching specific pvp rankings, on the release of patch 2.0.1 these will no longer require a pvp rank but instead you will use Honor Points and Battleground Marks as a form of currency to purchase the items.

The Stormwind Tabard looks really nice with this set particularly if you are going to be getting the shield as well.

Anybody have any suggestions for belt and/or cloak?

this is my favorite armor set in the game. to me it looks exactly how a knight in the alliance ought to look. i love the giant eagle on the shoulder and the piece of cloth draped on the other shoulder. plus, the helmet also makes your eyes glow blue. you get every piece you would need to give your character a "look" and the armor is bulky in all the right places.

bad ass set. especially considering it was created by the art team in vanilla.

i kept my set in my bank for pure vanity. now that transmogrification will come out next patch i know exactly what i'll be changing my armor to look like!

Are these pieces still worth getting? Depends if you plan to PvP at the 69 brackets for awhile before hitting 70 or 80. Even then, I would say only three pieces are worth getting for the first two set bonuses.

For two pieces, you get an additional 20 stamina, making these armor pieces competitive well into your 60s. While for your third piece, you get the highly important -5 secs off of Intercept; allowing Arms Warriors the use of 15 sec cooldown Intercepts for PvP! For Arms Warriors, Intercept is without doubt, your most IMPORTANT ability, as you can't kill what you can't catch up to; 5 secs off of Intercept can mean the difference between kill or be killed in PvP.

Like I said, these armor pieces are only worth getting if you plan to spend a lot of time in the 69 PvP bracket. Even then, only three pieces are worth getting for the important set bonuses. The three pieces I recommend obtaining are the shoulders, pants, and boots; because all three give +hit rating, a stat that is very difficult to amass in pre-70 gear.

I'm currently working on those pieces myself (already have the shoulders); sure it takes awhile to earn enough honor to obtain these pieces, but the 59 PvP bracket can be insanely fun to compete in at times, and is great experience to becoming a better PvP warrior when you're ready to move up to the major leagues.

With patch 4.3 coming out you can now take this set and Transmog it, giving it the stats of any gear you'd like. Saaaay.... Ruthless Gladiator?

What's a good tabard to go with this?

Loremaster and Scryer and the only decent ones I've found.

Possible matching belt: (Item #21692)

I was gutted when i couldn't use this to Transmogrify my gear with it as it looks absolutely awesome, so, i contacted a GM to find out why. Here is his answer

To be able to use this item set to Transmogrify, you need to have been a pvper in Vanilla and earned the title Knight or above under the old system. Then and only then you will be able to use this item set to Transmogrify your gear with. if you have not done this unfortunately you will not be able to do this.

But, if you go to Are 52 there is a vendor there that may be able to help you.

The vendor is already explained in these comments a few times so there is no reason to put a link to who he is.

Just scroll down lol

Hope this clears up for you why you can't TM this gear

Also here is a full explanation for you from Roraks link

The items out in the world (Marshals, Grand Marshals, High Warlord, etc) that use the level 60 PvP art are un-transmogrifiable (including the item level 115 stuff that shares the name from Burning Crusade).

In Area 52 a set of vendors has replaced the PvP Vendors who used to live there. Grex Brainboiler, Krixel Pinchwhistle, Tini Smalls, Kezzik the Striker, Big Zokk Torquewrench, and Leeni Smiley Smalls. These vendors sell new, transmogrifiable versions of the classic armor to players who have the Feat of Strength for Legionnaire/Knight-Captain or higher under the old PvP system.

There was a bug with the Feat of Strength granting access to these items, but was hotfixed within the last couple of minutes. If you meet the criteria log out and back in and you should be able to access the vendor.

The design intent with the Feat of Strength achievement requirement was specifically to limit these particular art styles to players who earned them through the OG (and relentlessly difficult) PvP honor system, while keeping the door open to reward them to more people in the future.

In a future patch the items sold by the Area 52 vendors will also be renamed Replica of to be more consistent with the items sold by the Darkmoon Faire theyre currently exact duplicates of the original items that allow transmogrification, which is obviously a bit confusing.

Potentially related, since hes in the same area, Kezzik the Striker sells inaccessible Season 1 Gladiators, Season 2 Merciless Gladiators, and Season 3 Vengeful Gladiators gear to all players, as the majority of that gear didnt have restrictions.

You can not use this set for transmog unless you have the feat of strength of "Warlord", "High Warlord", "Marshal" or "Field Marshal". If you do have the feat of strength, you have to buy a different set of gear to transmog it. I have confirmed that this is correct. This limitation was created so only characters with the feat of strength could wear this gear in transmog form because the actual gear is available for purchase with honor points to everyone. The transmog-able gear can be bought in Area 52 from, Leeni "smiley" smalls ((NPC #52533))

edit: apparently you only need "Legionnaire/Knight-Captain or higher under the old PvP system", quoted from a blue post on blizzard's forum (http://us.battle.net/wow/en/forum/topic/3657275742?page=9#178).
