I JUST had a game were I insantly killed MG squads, the only real delay is the PTRS acquiring it's target, at which point if you have 6-8 it's almost instant death for the MG. If you will notice in the posted video; when the cons actually start firing then MG dies very fast.
Alex for once I agree with you, I've been playing more since patch and people are abusing the ptrs. Either cons blob or guards blob, these kind of people are just as bad and probably the same people who blobbed volks. They need to be weeded out of the game for everyone's sake and the only way to do that is fix their ability to abuse game mechanics Relic is too slow to fix.
