Everything seems great to me. I'm elated by the fact that the current class system is going to stay (as I always thought, and I really don't know how some could think it would go).

The only thing i really don't like is the hate meter? I think it's unneeded and excessively hand-holding. Tanking should be a challenge, and a hate meter encourages too much to do "as little as possible" not to lose aggro, making the whole thing too mathematical.
