In games like Dragon Age/Morrowind (& Oblivion): I found Warriors to my liking.
Neverwinter nights: Paladin
In w.o.w : I preferred caster classes.
Fallout 3/ New Vegas : Ranged. Guns. Love them. LOVE GUNS. Not lazer pistols. Bullets! Smooth-talking, gun-toting, saint-like world-saver who wont take your money or possessions, even for the most dangerous mission. That's me, in every game. The 'good' guy.
TF2: Soldier
L4D/2 : Guns, not melee. I can't stand melee in L4D.
So, by looking at all that , I suppose you could say that I much prefer any 'ranged' class with a gun, staff, wand, throwing spear, blah blah blah. However, I usually try everything out in each game (each back story, each class, etc) to a certain extent, to give it a chance. If one flows well for me, that's my option. And apparently, it's usually caster/ranged.lol
