Naw you just need to be better simple as that. Plus EMP can disable VSAT so there is your counter. And for handy hand held counters tossing an EMP grenade also counters VSAT albeit shorter time period. If you got VSATed there is nobody else to blame but yourself seriously and your team. And if your continue to whine then so be it but all that leads to is more VSAT to your Butt and there is nothing that you can do about it but do the same to others.
Otherwise my theory is correct that you just plain suck and what are you going to do about it post on this message board and whine about or go play more COD so you can get better and suck less. Your choice dude or dudette.
