Also in the qualified but never bothered route (128 math, 148 english, 168 spatial.. go go shapes!).. what's an 8 year old going to do with an official Mensa coffee mug? Why pay a membership fee to spend time with people when there are plenty of just fine people in the neighborhood? That was my thinking anyway.
I do tend to play wizards and clerics, also I hate playing any character that has no way of puzzle logic thought stuff or can't rightfully voice my thoughts. I've become irritated in the past when the group is stuck on a problem (dealing with a person or puzzle) for 15 minutes and I can't point out what I'm pretty sure is the answer (not that i'm always correct- anything but!). That said.. I do have this nice idiot dwarf ranger right now who is great.
Then again, I also play these classes because most of my gaming buddies prefer the fighting and scouting classes. If there's a caster in the group, invariably it's me... I've just learned to enjoy filling the niche. Also take turns DMing.
