Curious of ED couldve been learned any ealier and how Bane into Deployment Tactics will work: Charges or different cooldowns its on a friendly or mob?

Other than that I have full endorsement for any rework either reimplementing Arcanist or evolving the job in some capacity. Showing the kind of understanding this is a job meant to go on adventure on, not stand around sucking your thumb waiting for other adventurers to get hurt on. You bring the pain solo, albeit a slow-ly working and drawn out death, and in party you do make sure nobody dies while also using your core functionality.

Some actually potential good and fun use out of the Fey Gauge, I think you've already shown more thought into this than SE did.

Love your Plans ABC and I think they would work even better as Stances, with short cooldown before you can exit or swap them. It might be my irrational fear of oGCDs after 4.0 and 5.0, but Id rather have something impactful available right away and the trick is to find the situation it would work best instead of being something you press every third minute like Chain strate and Seraph.
