I agree with Janet, exp has slowed down big time. As a bright wizard, I cant garuntee this, but i think they lowered Direct damage, but increased any DoT damage. my bolt is much wimpier, but my 2 dots just rape.
One tip I can suggest is when you first start, and in first 3 camps, usually level 1-6, if you click on nearly every npc you pass, you will gain exp from some of them for "You met Jim Bob", "You met a Dwarf", "You met a Rally master". Not a whole lot exp, but if you are ditching all the starter quests, and running straight to warcamp for pvp quests (like glen, and most healers should do imo) you can get to level 2 without killing a thing. small things like this make this game fun imo.
