I tend to play ranged support and damage classes, with a fondness for pets and turrets. I will be dabbling in Rift’s beta this week.
I could play to type and try to combine souls into a mage with ranged damage, a pet, healing, and buffs. I would have a large amount of experience to which to compare this character and how it plays. I would not add the unfamiliarity of a different role to a different game, mechanics, etc.
I could play against type and make a tank. I would have something relatively new to look forward to. I would not start with the “been there, done that” burnout of a character I have played in various versions for ten years.
I may not get much use out of healing, buffing, tanking, or taunting abilities unless I also become more social than usual and dive into grouping with unknown people who will disappear soon.
