It was cool(er) when there were MANY classes you couldn't play with one race, but now that trolls and dwarfs can play every class but one, it seems a little silly now. I understand the lore reasoning. Why would orcs have paladin trainers in the Valley of Trails? Why would there be druid trainers in Gnomeregan? Well, why are there Pandarens training everyone how to be monks? Why couldn't blood elf paladins be training all of the Horde to use the holy light?
