I mostly play casters... my girlfriend would ask me if I was sick if I would play a character which wouldn't eventually gain some spellcasting ability ^^;;
And when multiclassing... always with at least one casting class.
i've played an arcane spellcaster in 3e for a grand total of one session. i played a fighter/cleric up to 8th level, and only used my spells for healing. (a real man doesn't rely on magic to help him fight.)
I tend to play mainly fighter types, as I have an extreme dislike for the 'spells per day' magic system. hence, whenever I wish to play a spellcaster, I use my own variant mana system derived from SPD origins.
