As most fury warriors know, AP is very important for us in raids, to be able to compete for raid spots. Rampage was very important for a fury warr.. And now it is changed..
Rampage: Increases melee and ranged critical strike chance by 5% for the raid.
Sure it's good as hell, but warriors will have a hard time get enough AP without it.. :/
Maybe we will have it easier to get raid spots just because of the rampage raid/group buff, i don't know...
