Something I've noticed over the years is I seem to have a strong aversion to playing classes that get by on their wits and steel alone, like Fighters and Rogues. I've always struggled to find them interesting, especially since they don't really interact with the mystical or spiritual sides of the world played in. By the time a campaign reaches the end-game, a wizard and cleric will be discussing the complex magical doohickeys they need to realign to stop the BBEG, and the fighter's just standing around with a bored or confused look on their face.
I've always found more martial classes interesting if they've got some kind of "gimmick" like the Champion's god-given powers or the Magus' spells, and the recently released Thaumaturge is heavenly to me, where by contrast, Fighter and Rogue are classes I've only ever taken as supplements to other more magical classes so they're able to use swords and or to qualify for things like prestige classes in the olden days, and even then I've tried to avoid them in favor of more "gimmicky" classes that just seem inherently more interesting.
This, I feel, is a really bad habit to have for my roleplaying. The best roleplayers are the ones who can take any class and make an interesting character out of it, but I just feel like I'm going to spend any time out of combat or if there aren't any traps to disable standing around waiting while the interesting people are talking...how do I get over this?
