I can agree that guard break on arbalest would be great to have. Only issue is focusing all the power of Arb on buster cannon, it's already the best skill. I think it could stand to gain that power, but the other cannon skills should get a significant buff in turn

What? No, Blowback Cannon is leagues better than Buster atm, given the lower scaling on it, and the lack of a knockdown/knockback.

Buster lacks a lot compared to really both of either cannon skills tbh, nobody really minded this given buster was the entire identity before. Blowback Cannon is already like, one of the best skills in the game just objectively speaking, which is why I don't think Arbalest needs more in the damage department, just in the defensive and/or utility one.
