This is not CoD or BF - the weapons should stay faction specific. There shouldn't be any enemy weapons for heroes at all. Besides, I can't remember the last time when I was killed by russian mg. Its always russians running with MG34.. what is this? CoD?
Use your brain. Why do you think that is?
It is indicative of a balance issue if Allies have to use the MG34.
Have you even ever tried using the DP28? The gun does far too little damage.
