Hmm, could this work against OKW schreck blobberino into KT stall, I've seen that a few times now. It's a damn annoying style to play against, lock down 1/3 of the map with the schwerer to guarantee uncontested fuel income and run around the map a-moving with his schreck blob that hard counters all vehicles. Even when you know exactly what he's doing, the KT isn't exactly an easy thing to deal with.
Having double BARs on your rifles helps with the blob, but it's not a solution really - you bleed a shit ton of MP fighting with his blob. And you have to fight it, because he controls his share of the resources with the schwerer and you can't most of the time take it out or harrass his resources.
MGs vs the blob? Yeah, if it wasn't in the LT tier. If I go LT and the OKW player suddenly realizes he has one braincell left, he techs to Luchs and completely stomps me.
That strategy is why I think I'm going to start vetoing Langreskaya nothing sucks the fun out of COH2 like wasting 40 min fighting shrek blob over Center VP while MG34 spam makes any flanking tedious as hell only for KT to show up late to the party and roll over you.
M5 Quad still works to a degree but you need to be spot on with your kiting and a Puma can make your life hell if he goes that route.
