What is there to look forward too?

[Plunger]

Well I started this game in closed beta last year and quit around lvl 30, because I was all tied up with work in real life. I came back about a month ago or so and have already made 2 fresh lvl 40 characters. I have this question that keeps running around in my head though...Is there anything to look forward too at the later lvl's in this game? I find when I get to lvl 40 it seems like I have done about everything, besides kq's and quests. I don't really know how to ask this lol, but does the game stay as is pretty much. Are there dungeons to conquer? Some kinds of tournaments later on that I don't know about? Or is it just simply all grind/quest until you cap then thats it? If there is something that I could look forward too, please share :P I am in the process of making a 3rd lvl 40 character...I need motivation to get past that dumb lvl lol.
