What would you change about classic mechanics?

[pasi]

Most of the stuff I wanted to change got added in Luclin.

Class balance. Druids get mini-CHeal. Rangers become viable DPS. Casters stop sucking due to a combination of resists being lowered, AAs, and horses.
Gear mattering for non-warriors through vengeance, widespread FT, and focus effects.
Something to do at level cap (AAs).
Group and Raid buffing.
Bazaar (although, I didn't know I wanted this until they did it).
