World of Warcraft: Warlords of Draenor

Features: new zone (Draenor, aka the Burning Crusade planet, but as a cohesive whole set in an alternative universe/timeline), new max level (100), new character models, and the concept of a garrison for crafting/gearing up/progression. Abilities and skills for all classes are being streamlined, and (theoretically) CC should be less of an issue in PVP compared to the previous expansion.
