The chain knockback is something that most ground pvpers think is broken. There is no resistance from getting knocked down. There are a few small amount of people using it. Usually there is just one or 2 a night using it and when they do it is away from their team and they are easy pickings. Its still annoying, but in order to fix certain things in ground pvp... I think its going to take a major wipe and engine change on it.
I would say a good 50% of the time...its one or 2 people on a team that cause issues. Example one person on the team running into a group of 5 trying to uncloak and getting killed repeatly and they still do not listen or change strategy. I beam when I see this...its no fun trying to keep the same person alive or spending the whole match in team chat saying STOP.
