I'm not talking about 1 or 2 sniper, usually it's 3 or even 4 and they put such a manpower drain (and psychological effect) on you that it's not even funny...forget about going sherman, you will not have enough MP...
That's what I feared..
If your opponent can set a strat with 3/4 snipers in 1v1s, you're doing something wrong in early game. By the time he gets the 4 snipers, you should really be ahead..
Going straight 4 snipers in 2v2s is almost viable but in 1v1s it's not.. Let's say that your opponent goes 2 volks 1 mg and 4 snipers (whatever the build order)... that's a fucking lot of mp invested on T1, you can easily come with 2 m8 by the time he will get his first pak..
