I've heard TK was one of the funnest DPS specs in the game to play, but I'm kinda tired of DPS. I haven't really focused on playing a healer since vanilla WoW when I played a paladin so I'm kind of interested in that, plus I know you can solo a lot of heroic quests and finding groups for FPs is easier. I've just heard healing in this game is kinda boring.
Oh, and this is mainly for PvE.
Healing is not boring at all, but that depends on what you like and on the group you are healing, of course.
And yes you can take your saber strikes off your hotbars. You will never, ever use them.
