Lol crit buff is overpowered for every class accept the one that can cast it. An MA's fists just don't have the crit potential that the QL 1-200 weapons of choice do. Crit buffs have defined the entire game. As a matter of fact I don't think there is any single buff in the game that is used more as a cruch for pvp and pve.
There are probably hundreds of weapons in the game and due to crit buffs I would say probably 6 of them are actively used.
Think about it how many of you hardcore pvpers would go into 2ho to title hunt without it?
