I call it the IQ test gamemode
most of the time your team will either camp (aka usual enlisted gameplay) or zerg between each point, never defending
If you wanna win you can try to build your own rally somewhere roughly close to both points, in a way that makes getting out of it easy and fast (not some attic maze)
Try to get behind the objectives and kill off any enemy rally points you can get to
Then just stay on the enemy side, trying to keep them away from the points so that some of your teammates can eventually accidentally stumble onto them.
If you’ve got the zerg going, you just have to be in the opposite phase. Everyone RUSH B CYKA? you go hold A
Anyway, can’t win them all, so just try to have a nice game anyway lol
