Thanks for the info Alex. Looks like the maxim will be in good shape now. Ostheer will need to counter with snipers or mortars instead of just vet2 rifle nades. OKW will need to counter them with either IR halftrack with sturmpio flanks and/or the leIG, or go for the AaHT or stuka.
Honestly for OKW I think maxim spam is going to be a serious problem on some maps because of lack of flanking routes and the fact your indirect fire is locked behind a very large fuel cost. The new cheaper LeiG will be nice tho.
Flak Trak to counter maxim spam ain't going to work when the same tier building it comes from gives you an AT gun. But it isn't impossible.
