If these new Garrosh/female troll models are anything to go from (which they may be, if GC is to be believed), then just wow.... this could be the best feature ever added to WoW.
We spend 90% of our time looking at models in this game. Boss models, mob models, armor models, weapon models, the world itself... these are variables, changing wherever we go, but the one constant is our character. Many of us play character models from 2005, others from 2007, a special few from Cata onwards.
This is just my opinion, but i think this model revamp will be amazing. It will feel like a complete reboot. Shiny, new, high quality, finally bringign the flagship MMO up the standard of quality that it deserves, not held back by horribly outdated character models.
Im so excited for them.
