Aye, unless I play with a specific group of friends, I always go healer-tank hybrid. If I play with a dedicated group of friends, then I'll go full support.
I'll be sure to take that into account if I ever start playing mmo's again... But something tells me you both have had more people who don't know how to get out of the fire versus those who know what they're doing.
If it helps the tallying process, my character is a "pure mage" trope.
