I'm a defensive-play oriented gamer. I like to keep the fights slow and controlled. Battles of attrition are my forte; forcing both my allies and my enemies to play smart.
I traditionally play as support/healer classes or skill-sets when playing with friends. If playing an MMO solo, it tends to be more of a toss-up although I do tend to favor Classes or Skill-Sets with interesting mechanics.
My favorite MMOs of all time were Asheron's Call, WAR, and WoW. Though I found myself utterly sick of WoW currently.
I'm most looking forward to SW:ToR, FF14, and Earthrise.
