Very true, like I said, I don't disagree at all. Personally I just prefer saving it for the ice phase. We have 3 fury warriors, a Surv hunter, 2 ret pallies, me (prot war), as well as a few heavy hitters in the heavy burst aoe club that aren't coming to mind right off the bat (lol bat, bats) and the warriors are holding their recks for bats so they started getting annihilated once we got into phase 2 for the ~3rd time.
If I remember correctly on one of the better phase 2's the bats were dead when i still had ~6 seconds left on shockwave, and right before screech 6. I cant speak for who of our dps did/didn't pot I'm speaking from a tanking standpoint, where at ~300k+ AP from Vengeance another ~2k AP isn't going to do anything for me and I'll benefit more from using it before a taunt in the ice phase where my Veng. has fallen off already.
Should have clarified that earlier I thought I typed it in my head but apparently the thought didn't reach my keyboard lol.
