Your spam on threads regarding these 2 weapons will end in a HEAVY nerf on both of them.

BOTH of them are easy to use.BOTH of them kill way too effectively.
But it seems im the only one that doesnt have a problem with this.

I would prefer to leave them BOTH as they are and buff the rest of the weapons but if you insist, here are some fixes to balance both weapons:

MD:
Reducing the splash damage to 90-100 per slug, keeping blast radius the same.
Increasing direct hit damage to 350-400 for standard ones and about 550+ for the BREACH one.
Giving it Flaylock pistol shooting Arc for increased Direct hit chance.

This way MD wont be able to just KILL you with 2 slugs shooting at the floor, thing that seems to be the problem here.

AR's:
Regular ones:Revert damage back to how it was in chromosome. As ia recall the damage was around 31.5 - 35
. More than enough i say avoiding the spray and pray lucky hit kills. THIS or give the damn gun a recoil to work with XD.
Buff Burst and breach to usable levels.

There both weapons still very good.
Both weapons doing what they are intended to do but without the huge gap in effectiveness they have with other weapons.

Understand that starting a Nerf war for ARs and MD in the forums will end BAD... FOR BOTH SIDES...
So better think of balancing options , thinking from an objective point of view, for the better of the game we play and like.
My 2 cents.

ARs will never get nerfed, much less a heavy nerf.

Here's a radical idea: Wait until hit detection and aming get fixed before re-balancing.
