Ring and drape are some of the best you can get until BWL/AQ40 loot, and they're very easy to get. Just farm some rep in Cenarion Hold by doing the quests and with a couple AQ20 runs you'll have enough rep easily. The necessary items drop fairly commonly as well, besides the spiked handle.

In case you are wondering about the usefulness of the set bonus on a tank-directed set (considering the sum of the bonuses and all three), it's because, back in Vanilla, it was quite important for a Warrior to know how to stance dance. Intercept, being only used on Berserker Stance, could be used immediately after the GCD on the stance change due to a talent (Tactical Mastery: retain 5-25 rage when stance swapping, 5 pt). The set bonus could mean 3 more rage for another ability or 1 extra talent point to use on something else more productive.
