End of Content.. players are leaving

Lately i am seeing more and more high level players leaving the game. I think what is causing is, is a lack of content of game material after an certain level. The tipping point is clearly level 41, you get the Elite Soldiers and after that, its just more of the same. You also realize that making the buildings to produce the Xbows, Cannons and the Damascene Swords is rather pointless as you are getting ALL what you need from the adventures.

So, what now? I have never played an online game in which you can master EoC in a matter of MONTHS, which is clearly happening. Its sad to see such a nice game with such a lot of potentials going to waste :(
