Big developers only know how to earn more cash for their greedy asses and fuck up the game to its limits. Their way of thinking is fucked up. And yeah, new servers or better bandwitch now would be a huge pro for this game. I think you should highlight that Donate button more and even put some logo when logging into the game to donate. This has all of its potential. I know that one of the bittorrent tracker I am visiting(it is not one of those famous ones, but a local one, pretty small) is living only through donations. People donate through the whole month and in the end site owner can pay for all the server costs and whatnot. So yeah. Something like that.
I will even support the p2p idea if it helps you to improve the game a lot more. Something like 5$ a month is completely acceptable.
And don't you dare to parnter with Facebook while you don't get better servers
But really don't
The situation will be horrible then.
