Can you people never stop whining about weapons? I don't use a surge bolter; I don't even have one. However, it's threads like these that encourages devs to nerf the crap out of every single weapon in this game. I was in a match last night with some people using these surge bolters. I laughed. They run around cloaked while charging and I can see them. It takes them 3-4 shots to kill me. It takes me 1 shot with my courier to kill them. I would rather be in a map full of people using the bolters vs maps full of immunizers.
Also I agree with Notturno about the canker. Invaders are just as bad.
