The thing that bothers me most are all the people in conflict that camp, it has almost ruined that mode for me. Having 1 or 2 campers is standard, but when you have 6 players camping and 2 running around it can get really annoying.
Oh, and Docks boatroom camping wears on my nerves sometimes. Is it just me or is that level unfinished? There is that long side area that dead-ends and is mostly unused except for heroes/GG mode. Why didn't they make that connect to the boatroom area from the back or something?
