I tried mental controller once but with no self heals and the fact the fact that it was just so much squishier than my tank I just did not like it either. I also don't like having to stay out of range, which in the harder group missions you will have to do as a controller.
So yeah, so far fire tank all the way. I might try a healer someday due to the fact that they can have a decent survivability as well --- XboxLive Gamertag: VRiSBI NicK
yeah personally i like being a healer...theres a certain satisfaction in hanging off the fight and observing the state of your party and aiding them when needed....if you have a good tank you feel like a well oiled machine, infact if everyone does what theyre supposed to it can be poetry --- "its a bird....its a plane....its.......nope, just a bird"
