Seriously, though, BAR rifles vastly outperform Volksgrens for Anti-Infantry firepower. You're leaving out details or you're handling something poorly, somehow or other. I can't tell you what it is without a replay, but its something.
Personal experiences aside, it still doesn't address blobs. In another game, a friend and I had complete control of the map, only for the opposing squad to literally bunch 10+ units together and circle around the entire map like an unstoppable ball of death. This is even though I had an mg, at gun, utility car and bar squad in that specific location they pushed through.
Like our forces were nothing, made up of mg's and Shermans and mortars, etc. They rolled all the other points then pushed out King Tigers. I genuinely couldn't believe what my eyes were seeing.
