Spamming mgs should never ever be a valid tactic - anyone doing so should be able to be wiped off the field in the first few mintues. If this tactic is working in game it means the game is broken, as if that happened in vcoh as a strat the game would be over after the first flank.
They need to fire up voch play it for 10 mins and then come back to coh2 and make mg42 exactly the same, they had it completely right before stop messing with things that arent broken, this is what happens when you try to make a simplified version of coh on dow2 engine....
Yet spamming maxims is a valid tactic and it works unlike the mg .
