You can't move an account between servers.
For obvious reasons:
1- Imagine someone with an account at Server 5, level 120, runes, new heroes etc; you can't move it to a server like 10, which doesn't have runes.
2- Imagine you are in FP or Colisium challenger, in server 5, and whant to move to server 10,... same, where would they rank you?
3- Gree wants you to spend money to level your heroes, if they do what you want, they couldn't grab your money.
Level 39, jajajja come on, that is a very low level, start all over in a new server.
