I see all of the displeases about the new p2w only worlds, but I understand it. Even if inno didn't do that the game would die eventually. The problem this game has isn't the game or the premium you can buy in it, but the fact the people and especially children are getting lazier and lazier. They don't want to think about long-term politics, diplomatics and tactics which is(was) needed in this game. I'm not from the old school style but I want the non p2w worlds just because I don't have the money to win or the time to play on multiple worlds to get the pp I need to win.
But Innogames isn't the only one that sells content to make your game experience better. COD, Skyrim, Need for speed, ect. all sell DLC's which are basically the same as the premium features here, only packed in a way you don't think to much about it.
I don't want to make an excuse for their excessive premium promotion, but it is just something to stay on the market for a little longer. Although, this will chase away more players in the end.
One last suggestion, try to promote one server that is without additional premium on all the other servers. I'm playing here because the Dutch server has lost a huge amount of it's players long ago for the same reason. If you promote it on all the other servers it will get a huge amount of attention, that I can guarantee you. But I can predict already that Innogames won't do that because that server has a lower profit on the short term than the p2w.
Who knows, maybe the will actually listen to such a suggestion.
