Scep, you've played more wars than I have. How many times do battles last five-six rounds? What about five-six rounds uninterrupted pre-final battle? If we had a skill to isolate people for two turns of 1v1, sure, I'd have played poorly, but in practical terms we couldn't use Army of One because we didn't have the mobility to strike and run.
Rarely, but that's a circular argument. The only reason battles tend to be over more quickly is because a team can usually kill any other team in approximately four turns. That still doesn't deny another option.
