G'day
I played a 1e cleric in an badly-DMed trip to the Barrier Peaks back in 1983 or 1984, but it only lasted half a session, so I don't count that. And my first ever character was a Magic-User. Apart from that it has always been Fighters, Monks, Paladins, and Bards for me.
I guess that this might be because I often end up covering the weakness of a party after everyone else has chosen their favourite class. We usually end up short of combat ability, and needing either a part-time healer or a part-time caster of utility spells. In my last campaign but one as a character-player we were supposed to be playing spies, and ended up with no ranged fighter, no healer, no face man, not utility spellcaster, and no sneakthief. I played a bard to try to cover all those bases (and by the time we made 12th level he *rocked the house*).
