Bad news: obers are shit. and not worth getting.
Good news: volks are even more ridiculous at killing tanks and the puchpen and support gun are insanely good now.
Overall the okw got some pretty tasty buffs so obers i will replace them with something decent. like volks i guess
Interestingly enough, cruzz notes said that volks do not infact get 30% reload, but only 30% cooldown increase with vet 5. Which affects their rifle, but not the panzershreck.
