I'd be happy if they allowed server admins to add additional admins, auto balance/manually move players. And give admins the ability to spectate players. That, and have a favorite server list.
Remov the bot farm server spams (even though admittedly, I've used them). Though at this point it would be really salty for the ones who haven't used the bot farms to unlock weapons and attachments vs those who have. So what does EA do? Allow the bot farms? I feel like they should allow players to port over old offical maps from previous versions and allow full xp on them. Even if its on a rotation basis. Ie 1 month/week is bf3 next bf4 etc etc. That and allow limited xp on player made maps. Let us frag on our favorite maps from the past.
