I dunno about everyone else, but personally I would just kamikaze just to hear the general rage.
Or have all of my close friends be on my team and irc them all to just sit. And hug. For the entire match.
Really if you want an idea like this to work, the General needs actual power, which then ends up being that depending on what the general decides, that gives actual different physical limitations. For instance, if the general orders an air strike, the car garages de-spawn 75% of their vehicles and the aerial garages spawn 175% of their original bombers
Thus it results in different attack types, but not necissarily "stealth mode, half of you go stick your richard in a wall and see if the enemy will grasp you"
Not a practical idea, basically just an RP with guns. Which ends up being RP with random shooters
