In answer to the question, I have mostly played Wizards/Magic Users, although in recent years Clerics, Druids and Bards have appealed too (as alternative types of magic user, essentially).
The vote itself offers a fairly typical set of results, with Wizards, Rogues, Fighters and Rangers (more than Cleric) the most popular. No surprises here, although this list is becoming more standardized, and the spread of votes isn't that glaring really. There is scope to include all classes on the list. My caveats would be:
a) I still find the warlock and Warlord badly named - I'd prefer Witch and Noble.
b) The Sorcerer as per 3rd edition is really so similar to a Wizard it could really just be handled by the provision of 'Spontaneous Casting' Feats, and the like. They should be combined into one class.
c) Psionicists should only appear in setting specific supplements in my view, where Psionics is present.
d) Monks should be less overtly 'Eastern' insofar that they could represent a disciplined, unarmed ascetic from any culture.
So, for me, the final class list should be:
Assassin
Barbarian
Bard
Cleric
Druid
Fighter
Monk
Noble (Warlord)
Paladin
Ranger
Rogue
Witch (Warlock)
Wizard (incorporating Sorcerer)
...and I'd be very happy!
