ty for pointing that out.
before anything, i must say i dont know much about wotlk since i have such a long time i dont play it.
so lets look it this way.
a pala stuns u and pop every burst cd he has (eg wings, most bursts more than a minute cd, with about 20s busrt). u have an ability that reduces dmg with a 1 min cd, lasting 15 secs.
what should u do? reduce the dmg by 15% (its 30% but with santified wrath makes it 15%) or wait till he burst u to use it in the other burst?
its better to use shamistic rage at first because u want to use it again in battle. so u have no other option than use it early, and better when he is bursting u hard.
correct me if i am wrong, like i said, i have a rly long time without seeing wotlk. at least i can remeber a bit of cata stuff, but not wotlk.
greetings
edit:
another option to counter Wings is to bring some french fries. enjoy your serving of chicken wings with french fries.
