I fail to understand how those classes/races are "uncreative." A character is uncreative by his personality, temperament, background, etc.
Many of those posted there are not "uncreative," merely effective. Elves make good rangers. Halflings make good rogues. Dwarves make great fighters, and they have a charisma penalty. Half-Orcs favored class IS barbarian; is it any surprise that many of them are barbarians?
A player in my group ALWAYS tries to make 'original' characters, like drow monk/assassins, half dragon paladin/fighters, lantern archon clerics, tiefling rogue/wizards/Shadow Adepts, etc. His characters are always dull and unoriginal, because they have no personality.
I'll stick to my vanilla characters, thank you very much, and just add lots of hot fudge and caramel.
