The 1.2 nerfs are horrible. Full Telekinecs is turret speck and really sucks on pvp because you cannot move and casting times are pretty long. Balance/Telekinetics hybrid is pretty much gone in 1.2 and healing is nerfed too.
Guarding objectives in really hard alone or targeted. You cannot hide, you are squishy and your damage bases on dots. Dots can be removed and they do not have time to kill the attacker in most 1vs1. Try to win any hide char when he/she attacks you in shadows, try to kite melee dps chars with charge. It is easy to kill any player with low pvp gear or generally bad players. There are lot of better classes for objective playing.
I have to say re-roll a different class in 1.2 or leave the game.
