Almost every 1v1 I play against 20+ players is determined by which one of us snipes the power gens in first 3 mins or so using grenades.
There is no way to recover since the player who lost their gens will not reach t2 before the enemy gets vehicles leaving them with no possible way to produce AV.
Space marines are screwed since they have no way to pull this off, I suppose you could try and defend the power gens with a heavy bolter but it would likely just lose map control by wasting an entire squad.
