Biggest downside of donations is if some (mentally challenged) clan leaders donate a lot of stuff, they want something in return, other than the server and forum managed by us. Not saying that this is going to happen here, but it was the biggest Problem on Phoenix.
There is nothing worse than being dependent on money donated by people who would steer this community downhill. The trade off so far has always been "I give monez, you RESPECT me and I want to do what I want with my clan". Personally I'd rather cap the server to 100 players then having the same shitty situation imported from phoenix.
