Fortunately, AT vs Tiger is not a 100:0 matchup. It wasn't even so before. The world of RPS, whose hard counters are absolute, binary, and do not depend on complex mechanical interactions and micro, is not an appropriate analogy.
my point was that the range increase on the VI (particularly if vet2 does indeed give it 56.something range) gives AT weapons a LOT less range to operate in and the VI will already beat all of them if they get into the VI's weapon range. the other issue is that past 35 you must have something spot for the AT and unless that spotter has extended sight range (in general there aren't many options in that regard) then the spotter is being shot at by the VI which has an all purpose gun.
