Not sure how workable it is,and I wouldn't just use it in dust,but I really liked MAG's buff system when being close to a squad leader.

Now I wouldn't necessarily use buffs,but always wanted a system that rewarded you for tactical play.

A squad leader would have a zone around them that had "formation" indicators.If you were assault class,you would be asked to take a forward position,and you'd get a exp % increase based on the time you spent in formation.

Possibly the squad leader could set aggressive/defensive states on the fly.Set patrol zones using the map screen,highlight objectives,request spawn points locations,calling for vehicle backup and so on.
These would be shared on the map between the squads and players.


The main idea is not strictly tactical,it's also a communication tool among players,and could help push the idea that were doing this for each other and not just getting our own exp,but helping each other gain exp.

Added point values to things like stopping an enemy hacking a asset or point by killing them in the process. Or stopping an enemy's hack before it does complete. Things that reward a player for defending the points and assets not just running around trying to farm kills for points.

In the merc quarters, let our mercs to sit on the sofa and allow us to tune the big screen onto our favourite TV channel - the Dust Broadcasting Corporation - so we can watch other realtime battles raging (or past battles) while we chill, awaiting our next contract.

A Medic system like MAG's, symbols above both medic and person who needs reviving. Oh and make bleed out time longer to give people with med kits a chance to get there. Make rewards high for reviving to encourage it. (more xp in MAG for reviving than killing)
