Right now the capture time is very quick if no enemies are in the circle. But what if they took longer time to capture?
Zergs that capture would have to leave behind players to hold and defend the circle for the team to capture the objective, while the rest of the zerg moves on to the next structure. No longer would it capture faster if you have more people in the circle. each capture point has a specific timer to capture it. This would work better by eliminating the circle capture mechanics with a designated interaction capture mechanics.
This could be an experimental method of splitting up the zergs, and creating more defensive capture mechanics, as players would now need to defend places they are trying to capture until its fully captured. Enemy faction currently owning the structure could come back to defend the objective, which would lead to more fights spread out over the map.
