After Cataclysm, we've been introduced to some really awesome, new, Race Class Combos.
The following choices are made assuming ALL LORE is accounted for and makes sense, just pretend!
Lore aside, what race do you want to be what class the most?
No Draenei Warlock option for obvious reasons, I don't think creatures from other planets can be druids, so no Draenei Druid or Orc Druid listed either, same with an Undead Druid... Uh... lol.
