How much content is there?

I have been playing several toons since release and now I have found one I like more than the others I have began working through the missions. Myself and my friends seem to be completing on average 2 a night, sometimes 3. We are all now level 15 and are wondering what happens at 20, and when we have finished the missions to get to the temple of ages? Is it simply hunting in different zones, or is there more missions after this? The reason I ask is that I am enjoying it so much I dont want to finish it too soon and risk becoming bored lol as I am liking the missions alot more than just hunting.
Thanks in advance for any replies

Not sure what comes after 20, since I am only a 10, but there is always PvP, or your personal exploration of the lands. That is what I will do... just wander and then PvP. The graphics of the game a pretty enough, I wanna see what else is in the world.

I don't think the Temple of the Ages is the end but I don't want to spoil the surprise.

Thanks for the info....suprise huh

There's rather more content at 20 than at any other lvl.

maybe just tell me this, if i complete all missions to get to temple of ages and reach 20.....are there more missions after that?
