Imagine having 2 pistols, 2 smgs, 2 knifes, 2 shotguns, 2 machetes ( with The Expedition).
This type of playstile comes with new builds, new feats, new strategies.
We could make an desperado cowboy wielding 2 pistols, an S.W.A.T Enforcer blasting foes with dual smgs or just an agile murder with 2 knifes slashing foes left and right, and with new feats such as:
Rush: While Sprinting and using dual Smgs, Burst damage and duration is increased, but precision is much lower.
Slash-o-maniac: Wielding two knifes, action points is reduced if standing in front of an enemy.
Sit Down: Using dual shotguns, if surrounded by at least 3 enimies precision reduced but the damage is double.
Something like that, i aint a professional in feats, im sure it could be more and a lot more balenced.
