I keep losing kills to the fire on top of them. I'll grapple sombody and they'll hit the fire and die of natural causes. Please fix. Also, could you make it shorter so the assassin could perhaps jump over the top of it without catching fire? Would be awesome! Thanks Uber!
How exactly are you losing kills to the heat vents? You are going to have to go into more detail. As for your second suggestion, I'm going to have to disagree. I think that there should be some disadvantage to going above a base's defenses.
When people die from the fire on top of bot spawners or spawn doors, nobody gets a kill or even an assist, even if you almost killed them and hey flew up there. IMO, it should function like a ring-out and give whoever knocked them there the kill.
