Anyway, two thoughts:
1) I don't like tanks' AoE DPS/damage done being so off the leash in any case. GC has called it "weird and demoralizing" at least twice, and whenever I'm tanking, I agree. I wish damage were lower and threat modifiers higher.
2) With the above in mind, I think Thunder Clap itself could use a boost. I swear there's a palpable delay in snap threat after a Clap. I suspect it might be time elapsed before the first Deep Wounds tick, but in any case, the original attack has become more and more like a delivery system for the enhancement, and that doesn't feel right.
