It would be awesome if players can change their name ingame more times. I have my account for long time and i have nickname i don't like now. And there is nothing to do with it now

While I do understand this, as an alliance leader, I prefer the names do not change. I like knowing that if a poor or disruptive player known to me applies to my alliance, they haven't changed their name to sneak in again.
What is really needed is for the game, when choosing your username, to make known that it will be permanent and non-changeable.

@žukovský-tomáš If you have a good reason for a name change you can ask the support. Sometimes they help with that.
