I just got my MCH to have Gauss Barrel and I am having a lot more fun compared to BRD. I'm not going to go to how different the two jobs are but I just feel like it's a lot more active playing as a MCH compared to BRD. But at the same time, the rotation is a lot more strict, so there's the pressure there.

Ever since I got Gauss Barrel, I'm seeing an increase of DPS, even if a little. I'm used to the cast bars now once I got my timing on how much time I have to do my oGCD. And most of the time, using Quick Reload and Reload nullifies the cast bars for most of the skills, so I don't really feel much difference.

Only issue I got was with my first cycle of Wildfire. I can't seem to get the second Cleaner Shot to be in the Wildfire, but that's resolved now with the guide (thanks a lot!).

I gotta say that at first when I got the class, I hated it because it felt so clunky. But then I noticed a MCH (how rare they are), hitting quite large numbers so I decided hey, let's give it another chance. I would say... I'm glad I did.
