Simple concept.
Example: 10 Spartans inside the spire attacking against 1 defending. The capture timer currently doesn’t move. There should be a mechanic in game that slowly (343 would have to tune this) captures point proportional to more attackers vs defenders.
It could go both ways too. If the defenders drive back the attackers then move the capture percentage back.
In my opinion this give and take would force more players to push objective instead of float around perimeter.
