Some people are meant to tank, some are meant to heal, some are meant to DPS. Not to mention the 40+ minute wait times for queues. I know how yajinni feels. I hate tanking because everyone expects you to be perfect and fast. I much prefer healing with HB since I outheal everyone, or HB does anyway, lol. Even though I choose healer I still have to wait 20+ minutes most of the time.
I think a profile would be good for rep farming just to cut through the rigamarole of having to wait all those queue times over and over again.
