Steam Jacket is reset if there is no water maneuvers present, it's not a great switch to in danger attachment. I do agree with you that job ability delay is a hindrance for PUP and other jobs as well. I also agree that PUP could use more love to make it more competitive. I'd personally rather seem them boost PUP by removing the constant repetition of reapplying maneuvers once a minute. While also adding more potent attachments and either adding new frames with more attachment slots or just expanding slots in general. The biggest problem I see is that with any difficult content, the automaton's DPS falls dramatically because it cannot be buffed (sans COR rolls you'd only use in a pet party) or altered with food, which the current attachments do not make up for.

I think the major differences of opinion we have is the ratio of master/pet output. I agree on the problem but I don't agree on the exact solution. However, I respect your opinion.
