I actually found that weapon 2 damage quite bad, especially because of how it goes shoot shoot..... shoot shoot.
The reload rate also made me qq pretty hard o.o"
Gouf Ignited isn't actually that bad, but there's probably better choices. Think of it as a B rank Strike Noir with a weaker melee, A doulbe shot double pistol (as in Strike Noir's one click x2) and a whip that inflicts bullet zero instead of control shock.
How it shoots has nothing to how much damage it does...
And are you kidding me? 1800 damage is not enough for you on a B rock?
And it's reload is pretty standard for MGs.
