MY two cents, from having a 50 healer, tank and dps (one of each) i would say that though tanking is probably the most demanding, it's also the most rewarding/fun. I probably enjoy healing the most (overall) in this game, but when we succeed in down'ing an op boss or something and i'm on my tank, it feels amazing. I love the tanking in this game, and i hope it won't ever change.
Bioware, if you are listening, awesome design in tanking. please never revert back to zombie tanking like in wow, keep us engage in combat.
I cannot agree more.
"DPS is science, healing is art, tanking is strategy"
I'm totally stealing that, it's beautiful. :P
