After watching the new cinematic it dawned on me that Thrall is basically an arms Warrior now, what if this is a subtle hint that we may get multiclassing? It would be restricted to representing one class at a time but damn my main would have a lot more fun having 2 classes to swap between. Of course there is the issue of gearing and race restricted classes but I think if done right it could be cool and a huge boon to modern WoW considering almost every other MMO does this now.
