For the next expansion pack, would you rather have a new pai). races, or a new class, or a new continent/world to explore?
Races: One new race for Alliance, one new racefor Horde. Blizzard has very clearly stated that theor never going to try another "neutral" race for both factions ever again, so obviously they will go back to adding a pair of races.
Class: A new class to be added ingame (ie, Tinker). As usual, the class would be avilable to both Alliance and Horde, but only certain races can play them for lore reasons (obviously, a gnome could be a tinker, but a night elf wouldn"t).
Conitnent/World: Three out of four expansions so far have provided a new landmass to play in (Cata didnt add a.new continent but rather redesigned vanila content and added a few extra zones to them). A new continent or world would help further the story of the expansions plot and establish a theme.
