I get that it gets other to prop kill but as a T that would just be a deceiving tactic, plus, if you see someone prop kill you wont do the same as them, you'd kill them. I find that rule a bit over the top, even thought I don't encounter much prop killing when im on.
It's like a knife that needs more skill to use and doesn't leave DNA. Honestly, if you use props like I do, you are at an extreme disadvantage. That's what makes it fun. Also squishing people is satisfying. XD.
