Simple and Balanced Global/Supreme Commander Leadership System V.2 by inigma:
1. a global commander arises when 5 of 9 commanders pick one player for the role until voted out.
2. commanders are automatically selected by the system from the current pool of online squad or platoon leaders with the greatest number of members in their squad or platoon, with the highest command rank, and battle rank, and length of service in that order until 5 are selected, and no more than 9 designated. (players may opt out of being auto-selected by the system). Platoon leaders preferred over squad leaders. This way a cr3 player in charge of a 20 man platoon would be a commander vs a cr5 player squadding with only a single buddy.
3. gc is given ability to designate waypoints and map instructions visible to all players for the length of time they are online or until voted out in favor of a new gc. gc retains powers (even if offline) until a new gc is elected by 5 online commanders.
That's it. No other fluff.
Lead the largest platoon or largest squad online, gain a command spot. In a tie? Your cr and br and length of service will help you beat the other guy if the 9 commander spots are already all full. Once a commander, you get to vote for gc, even for yourself if you want.
