since we're talking about a fantasy here,

a decent voting system, something like tribes

ability to ban people without CK's auto kick, too many servers don't have it

more realistic grenades, i get tired of seeing suicide bombers running around the map with live grenades that never go off until they die, when you pull the pin the timer should start then. would also make for nice nadings where you actually have to use some skill in them

fix the leaning system, every time someone starts firing their STG or KAR entirely through a wall with no part of them visible to hit and starts killing my team i want to unscrew their head and shit down their neck

oh, and how about a fucking sdk i don't have to buy?
