“If it ain’t broke, don’t fix it” There is a healthy economy with enhancement cores, master working for super energy and taking charge builds, this also impacts explosive light weapons as a replacement for vorpal weapon. Putting in helmet slot also hurts energy economy of armor mods which ruins gameplay. Someone suggested utilizing ghost mod as an alternative. What will be the benefit of master working a weapon other than a kill track and a stat boost which barely buffs the gun? Masterworking has long been established as a way to get better gameplay performance as a reward for killing with that weapon and as build option. It makes no sense to gut that system with this change.
