The most annoying problem in the beta for me
In the heat of battle with a lot of marines, players get flung up in the air and pushed everywhere, making it very hard to aim or do anything. Even going to weld a fellow marine is a chore as when you touch them they fly up in the air too. Moving in groups is supposed to be an advantage for marines, but often it's a disadvantage with the collision problems right now. I hope this is fixed soon.
