Some of your suggestions are solid. There are too many maps on the server and too many of them are shit. Just going through the nomination list is hard because it's not even organized alphabetically. The tryhard maps don't work and nobody knows how to play them anyway.

Rank: doesn't matter to 99% of the players on the server. You can remove it, change it, or leave it the way it is and it won't matter to more than a few dozen people. Low priority.

Special donator class: could be a good idea but leave out the stupid shit that makes GFL and PF so obnoxious like bright, ugly chat colors, custom user titles and skins, and pay-to-win garbage like being able to jump higher. Just a simple reserved slot and some other reasonable perks should be enough.

Community: many people are backbiting assholes here. True enough. We should all aspire to be more like Meltdown, who treats everyone with respect and never talks shit.
