Mechanics that reward skill not numbers of players. Multiple play styles with the ability to customise loadouts (no classes with stale loadouts), pacing, balance and teamplay that doesn't negate solo pwnage. A skilled player should be able to go through multiple foes.
Clever map design, not repetitive, breakable choke points and flank distractions (with a clear indication of where the front line is, so you don't get shot in the back all the time) coupled with secondary and tertiary objectives. Several meta objectives that are non combative and CAN affect the overall outcome, albeit not on a devastating level.
