AAHT will have the greatest effect in 1v1, simply because paks can only defend part of the map. The rest of the map will be open slather for the AAHT. The problem I see is AAHT will be able to patrol the edges while Sov indirect fire pounds the Ost fortified position..
That's nearly how I played it during my 1v1 tests. The abilty to reinforce your distant squads while "visiting" the edge of the map made it even better. And holy shit, the quad is damn fast.
And it vets extremly fast, too.
Paks are only getting an issue if you're making a crucial mistake or he oneshots the quad with 2 Paks. But that never happens, because its really easy to keep Cons in Front of the quad, which gets even better with sandbags.
And if he gets 2 paks he basically lost all mapcontrol because of the heavy mp investment, cause he needs to guard these things very well.
