I dont know if that is true as you provide no video evidence.
I can speculate PTRS might affect ambient world objects which shift and crush models and HMGs.
You have to keep in mind that the video porygon posted was arranged.
I just used Fraps and record this 10 seconds of HMG got destroyed, of my own replay, of my Cons doing this in a 2v2 automatch, in order to prove its overpowerness, and you response with this.
1) There is no evidence proving it.
2) You claimed it is half a minute, THE FUCKING VIDEO ITSELF last for 28 fucking seconds, while the engagement last for 10 seconds.
3) You claim I arranged this, I make this hur? Sure.
Sir, you are a great, great, M-O-R-O-N.
