My problems with this...A lot.

The GCDs. Personally I see SMN as the caster that barely does any casting, which is true because most of its skills and damage come from oGCDs. Literally our only (relevant) casted spells are Ruin III and Miasma III, Ruin III being only its spam-able filler spell because it somewhat needs to cast things as a caster. Adding more GCDs would honestly just mess with the job identity, plus SMN already has mobility problems.

The pets. I really don't like the idea where they do attacks in a sequence by themselves. Even though I hate Egi Assault, I still like that I can control my summons. Also the Egi Assault rework really doesn't fix the problem, since they're still a frequent 30s for both but now it's not a oGCD so it's more annoying to manage.

Then there's Aetherpact/Devotion. You basically just made it worse because it's now a cooldown on top of another cooldown now that the pets aren't permanent. It'll make it even more of a hassle to time it nicely.
