I'm fond of things that get me out of wearing armor.
I just can't stand a character that wears armor.
So for the 'fighter type' my current character is a human Archer / Noble. Classes from Sovereign Stone. Noble's get to add their CHA bonus to AC like a Monk does with Wisdom. The Archer half puts me at a distance since I tend to feel anyone who engages the enemy up close is an idiot, was unprepared or had poor recon (which is all kind of the same thing).
Another combination I'm considering if the group ever uses FR again is an elven monk / Druid of Miliki. Which of course requires an alignment change at level 2. Again gets me out of armor and let me use the weapons I think a Druid would logically use based on my own understanding of the concept, since Miliki is one of 'Greenwood's wetdreams' and thus her Druids have no weapon restrictions.
Otherwise my usual standby would involve something magical. I never liked Wizards with their spell books so when 3E showed up with the Sorcerer I finally had something to play on that angle...
I've been trying to find an angle on a half-orc that I like but I've yet to hit on it. Conceptually they're my favorite core book race but I seem to be lacking in good concepts for them.
Outside of the core rules I'm a fae fanatic, but the game offers so few choices for me in that arena. All that's out there is the Fairy from Mythic Races and it's got a lot of issues over it's ECL which most people find too high at +3. Self included. The author actually submitted it as +0 but that got edited without removing the things he'd put in to balance it down to +0.
If I ever find myself in an OA game (which I doubt) I'm fairly certain I'll end up with a Naga (Rokugan book). Probably shaman.
