I don't know why people are unhappy or saying its the wrong kinda buff.....its a great buff and boosting active abilities so they chose the right stuff to buff (although again I would have preferred to spread the buffs by shifting some of the damage increase from SS/LL and boosting ULE and shocks some more....tho I guess the MQ increase does help shocks). All those specs listed that got buffs have been underperforming and you can see them at the bottom of the charts on stuff like raidbots so those classes/specs needed to get a damage boost.
Not sure how much more or less Enhance got buffed compared to those other classes though. Classes like ret and feral got a straight +%damage buff while ours is thru individual abilities...my guess is to keep our auto attack and stuff like imbues from doing too much damage. I would consider this a "massive buff" tho, cause its basically 20% more damage to SS, LL, and MQ (~18%).....thats pretty solid.
