They need to be buff there root only last 10 sec if you hit the person that you root it brakes are silence last 1 sec and healers and other class get skill that make immune from silence for 10 sec. There dps for pvp isn't bad but what will happen is you get ether sleep for 30 sec or rooted by a melee and will be foucs attck form everyone and wont be able to do anything about it because there root don't brake on attck. and its hard to kite as a bard the fact melee can easly run you down. honestly im thinking of rr my self
