Deadly grace is still much better for us (in reference to raids). The new pots are only good if you're in need of some quick burst damage.
I don't know if I agree with that. I've seen Old War do 5-10% of my total damage, deadly grace hasn't come close to that.
Generally the new stat potion is best for dungeon aoe pulls and for almost all the classes deadly grace / old war still remain the best for raiding.
I like the new potions, especially when you have to be close to the boss on pulls like spider boss.
well your first statement still didn't make much sense because just general "quick burst damage" is not what the new potion provides, its what the old potion gives you.
You're right with the 30-60second window, so I thought about it but I don't see it anywhere being the case.
The only other reason I'd prefer the new pot over the old ones is that it gives you stamina aswell.
Getting 2,5k extra stamina during double dryad waves on cenarius for example is probably worth more than a little bit more damage from deadly grace/old war.
