@VRL: Sov tier is calculated according to how many buildings you build. It is not a linear progression as is Sovs. You CAN build Katyushas by Sov T3. At equivalent tier, Ost can build only 81mm Mortar.
Ost doesn't have to build every building either. So you can get Pwerfers by tier 3, according to your laughable logic.
@Marxist: Bunkers are non-existant in 1v1 meta. Disregarded. Go back to 4v4.
Acting like they don't exist is intellectually dishonest and exemplifies just how weak your argument really is. Keep reaching.
