Well, so here we go again in this way.. topic for each weapon..
I think it's the most orginaized way..
The HK Mp5 is overpowered in some people's oppinion.. it's realy good in close ranges, you could just keep spraying with it..
I think GD's idea of nerfing it is just fine.. here it is :

"HK MP5
Damage: -5
Speed: -3
was too powerful, should be solved, see discussion thread."

Please state your oppinion about this weapon and the new settings.
