Gamer ive been dropping VM users all day with all kinds of primaries the tf you mean the only counters use special ammo? All you gotta do it hit your shots at long range with a pulse or scout or be very annoying up close with either a side arm, last word, or an smg. Close range they might as well swap to a shotgun to deal with you because up close vex cant kill like it does at mid and at long range they have to be put in the open leaving them for teamshotting or getting beamed by a gun thats more accurate and kills faster which do exist btw. I say that assuming you dont know since everyone thinks VM's TTK is so fast.
