Hmmm, I don't play SMN anymore, so I will give my feedback about what would make me come back to this job:

I. Pet Overhaul
The pets are wrongly behaving and should not be a hassle to deal with and I see 3 ways:
-Pets are completely automatic and just attack like the old auto-turret. Sad to say, but summon and forget.
-Pets are completely SMN dependant and don't have their own attacks. SMN cast devotion? The pet obey the order within half a second.
-Or pets are recoded for a mix of the solution above, they still attack but obey the orders way faster.

That goes for Egi and Demi, so no more Bleeding GCDs.


II. Reconnect the rotation and reduce filler phases
SMN rotation is kind of a mess but also seems to be a good start something good. Trance Bahamut is in a weird spot where it's just to prepare Ahk Morn.
In my opinion, without going in details, SMN should look like a bit BRD.

Different phases, that starts/end with a dot refresh through Tri Disaster.
If we take the actual rotation, SMN has massive filler phases between Demi on a 120s rotation.
With a (maybe) 3rd Demi, the global rotation could shorten the filler phases.
