The reason I do it isn't because of those reasons. If they try to kill me and I kill them in such a badass way such as: dodging bullets, killing them with a sliver of health left, or the best and most frequent way...getting teamed on and coming out on top. If I start fighting 2 people at once in a flat area and can kill them both without losing half my hp, I think everyone would teebag the opponent's corpse at that point. Your in that situation of "yes suck it!! I can't believe I did that!" And it feels pretty good lol
