"(figuratively) Not connected, coherent, or continuous." Nothing in newSMN is "connected", it's an incoherent ("united as or forming a whole.") design as every individual design element exists separated mechanically from the others. The closest you get it that Demi summons give you gems, wow truly fantastic.
You should honestly be glad I ignored your post because it's not very good. For example:
You directly describe how HW SMN systems feed into each other synergistically. Aetherflow gives you Aethertrail, Aethertrail gives you Dreadwyrm Trance, Contagion still existed to link your Egi with your DoTs and your Trance. Was it somewhat devoid of classic ff SMN-theme/feel? Sure, but it was objectively a more nuanced and interconnected design.
You don't say anything in the SB paragraph, you just describe how Demi-Bahamut worked. This iteration of Demi-Bahamut could at least be considered "obtuse" which could be strung tangentially to a semi-out-of-context definition of disjointed. Current Demi-Bahamut just sits there and shoots after you press a button. This is disconnected from the rest of the kit compared to SB and ShB Demis.
Non-directional descriptions again. 2 minute meta is only a problem because EVERY job adheres to it, which is what makes it a meta at all, also Devotion was on a 3min CD anyway. Trance CD was 55s. Adding Dreadwyrm Trance's duration gave you lots of flexibility outside of that 2min cycle. You even admit in this paragraph you don't know where Further Ruin came from before lol (15%proc on Egi attacks). Calling newRuin 4 an element of cohesive design because you use it for movement while saying Egis don't do anything is mint.
And then you have 3 paragraphs of "newSMN is totally not disjointed, look at how well the kit slides over a smooth brain". Aetherflow doesn't even have DoTs to interact with, Bahamut and Phoenix don't give a fuck about you anymore and may as well just be the same summon (people would probably like it more if they were, as they would either get more consistent utility or another Deathflare to press), the Gems don't give a fuck about each other, Carbuncle is lobotomized, Your filler is all vanilla GCDs that only involve flat potency, oGCDs are also purely flavourless potency other than Energy Drain which gives you...well you know. How is this in any universe a more interconnected kit. It's a failure unless their only metric for success for the rework was accessibility, and maybe popularity, but we don't have the SE official #s for that and never will.
