Yes I really am aware that it has quite a few downsides. Even tho I think that it is a step that could change it for the majority of servers, being that new players cant differ between Epona or Belenus for example, so if they wont be able to join Epona, its ok because it doesnt affect them and in the long run they'll populate smaller servers and then u could reopen the sign up for the big servers.On the downside if you got friends or family into the game and you were fortunate to be in a well populated server you wouldn't be able to enjoy the game with them.I suggested couple of years ago that OTM close the option to make accounts at certain servers that are very well populated and thriving. Not to hurt these servers, nor permanently, but simply to give us the smaller servers a chance.
Its not an easy step or one that should be done recklessly, but I believe its one idea that can be a major fix.
