Too few players for 8 servers... Look how poorly com8 has done. And other servers are barely getting 2-3 good kingdoms.
If travian team focused more on quality of servers over the quantity I believe it would reinvigorate more players to come back. Strategy games thrive on competition not easy wins. Things like a quicker app and new tribe or tournament server is what is needed. Close down com 8 and 7 and push out updates quicker. A couple of patches a year is killing kingdoms. Been in beta forever now for what should be a pretty simple to update game (coming from a mid-level dev).
It's always the same complaints I hear on private forums.
