There problem with MCH basically comes down to RNG and the Gauss Barrel. With Increased Action Damage and our turret, our potencies are on par with other classes damage. The problem is that GB, which is supposed to increase our damage at the cost of mobility is currently flawed. We actually suffer a dps loss because the 20% and Gauss Round don't make up for the loss of auto-attacks. There's also too much downtime between ammo stacks where you're just spamming a low potency ability and praying.

And does anyone know if GB is additive or multiplicative with Increased Action Damage? If it's the latter, it's even worse.
