A lot to digest here, more importantly all of it seems too vague to take seriously, but firstly

Selecting a JOB that requires a job stone would never happen at the beginning Arcanist is a class that evolves into either SMN or SCH. No jobs exist that are level 1 (as much as I’d love for them to try to give new players a chance to level new jobs) or at the very least have SCH sever its tie from via SMN leveling.

Pet AI can’t be fixed because Egi’s are gone, and once again Egi are so closely tied to the lore and progression kit they’d have to rewrite the jobs lore and quests to make it make sense for the context of the kit

Pets automatically doing their rotation seems pointless, and as engaging as placing Bio on your enemies. As “flashy and cool” as they can be it’ll be as fun realistically as Queen is for MCH or Living shadow for DRK. Toothless and loose and a downgrade

“They do more damage with less effort?” “100 button rotation?” Im starting to think you never leveled either job or mastered them because these are more or less exaggerations not issues.

You understand one issue with Pet Ai but I don’t think you understand what makes jobs good, the line between poor design and engagement. If you did you’d be more specific instead of list a fever dream of all the dated non-SMN mains issues which boil down to “make them cool looking” which time and time again doesn’t fix jack Schit
