The Obers didnt recieve a massive nerf, we have not seen them yet but they should remain fine if people buy the lmgs on them (which still fire on the move, and obers still dodge bullets). Their price might get adjusted in the next patch but they are long ranged super infantry whom can sit back and out dps almost anything.
Dude a quick look on the dps charts and you will see that volks are better infantry if the mp cost remain the same. dont even get me started when you compare them to fsj's or fusiliers. mp need to be dropped to 280-300 or i will never touch this infantry again.
