They are great if used properly but that use is really just gey. The only use of them I condone really is for a guy who's running in and out of doors so they can be killed or for flag rushers. Ways to solve this would be making it so they can't be placed within a certain distance of eachother and within a certain distance of a door. They might as well either do that or just nerf them like they did crates, crates used to be insane because there weren't any explosives they couldn't be picked up and the fastest melee was a machete now they're completely useless.
