For those that care,
Play competive which is 5 vs 5, or setup a private match with max team 5. Every game I jump into where there is 8 vs 8, it seems to lag quite bad soon as players start to join.
I'm trying to get a 5 vs 5 going so add me and send message saying you play brink. I got about 5 regular players so far.
No one searchs for competitive so thats why I started this post. I'm always waiting by myself in game. Found 3 today and game ran smoother than 8 bots single player.
