Thanks a bunch!

IRL you'll have enough of options to configure any load-out you would like, balanced or not. That's just a fact. Why can't we have this possibility to choose here?

On top, ArmA is a game. Tough, but still a game. So balance has to be mentioned. As I said, for many communities it's critical, since they do create pvp-missions for their members, and they DO want each member to have same level of fun (on both sides in the mission), not suffering from over-killing items in the game.

I really want to suffer just from crappy mission makers, but not because somebody will say: one side was meant to win because of their assets.

So coming back to the topic, we just want to have possibility to choose, so each community/server/player can find whatever he likes.

That's obvious for factions to have more or less balanced weapons, including LMGs/MMGs. Thus it sounds logical to improve the current list of MGs available.
And I bet for many communities, it's not just "nice to have", but it's critical from PVP mission-creation point of view.
