I can agree that moving it to a gcd might not be to someones tastes, but having them as a gcd does not make them more annoying, as they would just be replacing a ruin 3 in the rotation. I wouldnt say it ruins the identity either as it used to have more gcds in previous expacs and that didnt ruin smns identity

Again the control thing is purely subjective, I currently dont really feel in control of them, because egi assualt just feels like a ruin 4 proc button. So i prioritised the assaults being impactful over "in control", plus it brings them in line more with how summons worked in classic ff.

I dont understand your final complaint, they should line up perfectly fine. As a gnb main lining up ogcds for your timered gcds isnt an issue ever, and with egi assualt 1 and 2 being charged and summon support being a dps loss otherwise, it seems like a relatively easy and painless thing to track. Only thing i would say is maybe just have devotion summon titan to do the ability in this case would work fine
