Personally I feel flash point shouldve been more dynamic and constantly cycling.
Instead of capping a point entirely until its full before moving to the next, the points shouldve been active for a finite time, however much either team can capture in that time frame is what you get before cycling onto the next point.
While in control, a meter fills- First to fill it to 100% wins.
Possibly have it so that a team can only cap a particular max off of any 1 point, 33-55~ %. If you hit that amount off of a single point and theres still “time left” on the point before cycling to the next one- Automatic close down and the next point randomly opens up.
