I'm totally a ranged type. I loved, however, in NWN making a ranger/fighter multiclass. But for base classes, I love rangers. :)

I prefer playing as a wizard because casting spells from far-away distances always does the trick for when you don't want to get yourself killed fighting a tough monster with only either a staff or dagger.

Myself, I cannot stand mage-type classes in any game. Being restricted by mana, spell choices, and typically weak in close range combat, or if taken by surprise, is just not something for me. I've always enjoyed playing a class that can freely run around the field without worry of getting shot down in a few hits.

healers and heavy support classes:) i must be important in any group and i must be able to change the tide of battle :)

i tend to like mage archetypes, because anyone in real life could (hopefully wont) weild a big sword/hammer or some daggers and stab people, but they cant shoot fire out of their hands!
also i like the ranged viewpoint because i can pay attention to more of the battle that way, if you're up close to someone it's hard to see what his buddy is doing or if reinforcements are rushing over the hills.

healers can be fun too. i like to have some power over the lives of my allies as well as the lives of my enemies.

The fighter. I dunno, but it's usually simpler for me. Though, a good ranger is pretty fun too.

After trying out a lot of archetypes the last couple of years, I know that I like the tougher classes the most.
Their role shouldn't really matter much; either Tanking role or some kind of Hybrid.
I just don't like weaker classes or roles. Also I'm a big melee fan!
