A new server is very tempting, the idea being that players can bring their experience and take a shorter path to success. Buy a 1000 cents package, swipe all the best heroes and port close to 16's or dare I say, the 18? Otherwise, you are better off on the server you are already on.

Going through the 6 pages of this thread, HH's are cited as primary reasons to switch.
Evony should pay attention to these things and find ways to make money.
