Which part of summoner's rotation am I meant to find satisfying?

No they are not bringing back ruin stacking and honestly speaking if 6 gem summons with *unique* astral flow mechanics each are not enough then I start to wonder where the limit actually lies for you. In terms of something to build up to, especially for higher level gameplay, how about a gauge to fill (faster when doing the casted summons, slower when doing the instant ones) by executing astral flow abilities that culminates in being able to choose between Alexander or Odin depending on the situation at hand.

Ideally, this would have been where the job stood by Shadowbringers at the very least. "Light and Dark" expansion would have been the perfect time for the primals of light and darkness to be added to the job, with Alexander naturally being the heavier damage summon at the cost of cast timers and Odin being the swifter yet weaker one.

My limit is having flexibility with the basic spells (having casted and insta cast spells both at our disposal). Not being capped by a number of gems stacks per summon to use these basic spells but instead having a actual timer on each summon where we're free to use them. More oGCD abilities coming out from the summons during these windows instead of the SMN using them directly (I want to command my summons to execute them) and having a proper burst phase where we build up something during gem summons.
You see, I want flexibility and room for growth within the job skill set with a proper learning curve. Those are things that current SMN definitely lack and should've already been here with this rework. So, right now, it's just an unfinished rework that needs a lot revisions imo.
