Well, in 1v1 its same thing. You can get amazing map control as USF, few shermans etc but in the end you will win by VPs losing almost all army or OKW guy will make come back. Just watch Sage vs Paul. I think 30vps more and Paul would won.
For me it's bad design if one faction needs to win early game because in late game you will be rekt.
late game in both gamdemodes starts at around the 20 minute mark. it's just a whole lot easier to stretch out late game in 1v1 than it is in 2v2
