I'd like to start off by stating that I don't know how to properly balance this this is merely my ideas on how to help these roles and their current issues.
To start summons are no longer commendable and don't remain in battle the whole time. instead all summon work just like MCH's turrets/queen and DRK's shadow in that they are summoned do their bit and then vanish after a time. All summons are on a 60s CD and when summoned they are on the field for 15s. Now rather then explaining it first i will put the the skill rework and then explain it.
FYI Underline means current summon and Italicized means added/changed through trait.

Basically my plan for SMN is to make summoning the focus of the job by making it so that you have to rotate your egis. Each is only out for 15s and on a 60s CD. Once you introduce Trances the SMN's rotation ends up being 60s or if you count both demis a 120s rotation. I added the concept of egi-aether. In a way you can look at is like another form of aetherflow but you get one evertime you summon an egi. ou use this aether to enter DWT and FBT. I also wanted to make DWT and Bahamut one as I found it weird that they were separate yet FBT and Phoenix were one. Your rotation ends up being 45s of egi rotation , DWT for 15s, 45s of egi rotation, FBT 15s, and repeat. I also changed Enkindle to be like rook/queen overdrive as now your egis/demis will auto use their big attack before they leave and Enkindle is only meant to to make them use them for situation were they wont be able to perform them because the boss went invuln. And Speaking of Enkindle since it is no longer the lv50 skill i have given SMN a new Skill that is suppose to be all three Egi Enkindles combined essentially.Egi assault has also been changed into one assault but when used two egis, the ones not currently out, will perform their assault actions. Overall this is meant to remove pet AI by making it just automatic like rook/queen/shadow. Yes you as the summoner no longer actually "command" your pets but with the way AI works commanding them just doesn't work properly.

lv80 Enkindle Seraph Order Seraph to perform Consolation. Seraph is withdrawn upon execution.
Traits
lv50 Enhanced Eos - Eos performs Solace just before withdrawing from battle.
Sch is mostly the same but Eos is now just a cooldown pet to be summoned every 60s and only out for 15s. Selene however is now the fairy that get's used to perform fairy abilities. This is to help out with AI so that Eos can focus on her healing and you can still command Selene to do her bit. Now for Seraph, she now requires faerie gauge to summon but i think 30 is too much and Seraph only prevents Eos from being summoned so you still have access to Selene and all her abilities. Enkindle Eos and Solace are just a added ability to give Eos a little something to help spice her up, thik of it like Consolation just only a shield and no healing. Lastly Enkindle Seraph just forces to use Consolation immediately at the cost of her being withdrawn, also just like the Egis/Demis Seraph will auto use Consolation just before she her duration ends. You know her finisher. T think these changes also make low lv SCH pay more attention to healing and less of them just letting Eos do all the work.
