Bert I'd rethink that, Rift is looking quite nice at the moment. And with an open beta just around the corner it wouldn't be a bad idea to just give it a chance.
I was able to play in a few of the earlier betas and quite honestly after the first mass invasion I was sold.

And you want to talk about character diversity... there are 2 factions 3 races per faction 4 class archetypes (Warrior, Rogue, Cleric, Mage) , and each archetype has a set of 8 sub-classes. (A character's spec can utilize up to 3 sub-classes per spec) 32 sub-classes total, each with full 50+ point talent trees, but alas no you can't mix and match sub-classes of different archetypes.
