I think the HMG's are where they should be now. The problem i see is that people aren't used to flanking or have trouble keeping the flank, because its easy to make a small micro mistakes and you are forced back with nothing gained. I totally understand why people get frustrated, but to play vs a good player that has good MG micro, is gonna take alot of patience and micro to beat. But hard games like that, give more pleasure than frustrating moments when you can't hold your ground because your mg doesnt do shi#.
I think it's more rewarding to flank the mg and to succeed, than to just run in with a blob and run over a crowdcontrol unit.
Alot has changed, no it's not CoH1 but i would say the game is great. Team games are more fun than 1v1. But the game itself is being improved in every few months, it's getting there.
