I find AA truck not as annoying as it was mainly because you can afford to equip these Volks with Shrecks now and throw some grenades in the mean time.
Also Puma counters it quite heavily right now.
Ammunition buff is the biggest one for OKW and it changes the faction completely. Suddenly Maxim spam is not an issue for me and Infantry blobs are easier to deal with. I hope it's not a placebo effect.
I like how noone gives a flying fu*k about wehr. There's almost nothing proper to counter it expect a pak which is bullshit because any decent us player wont come anywhere close to where pak might be and use the halftrack to gain the upper hand in resources.
