You seem rather uninformed. The stat squish doesn't affect gameplay whatsoever. It's designed to be unnoticeable and is just a little service for us OCD people who don't like huge numbers flashing up on our screens. The level scaling (which you seem to obliquely mention) is not actually being implemented in WoD and even if it were it would be entirely optional. Assets are not being reused (or at least no more than they've been reused in every single expansion in this game's history.). Nothing frustrates me more than people claiming that just because Draenor = Outlands that it's all rehashed. 9 months without new content sucks and I really hope they get things together next time, but it's actually an improvement over Wrath and Cata. The only point where you're correct is the lack of new races or classes. I confess I'm a bit disappointed but it's perfectly justified. New character models, class balance, story focus, and low numbers for Monks and Pandaren are all good reasons why there is no new race or class.
