Summoner in those other games can use their pick of summons. We are currently about 30 primals in with FFXIV. And we only summon the 3 Egis and 2 Demis. The framework would be fine for level 50/60, but building with only 5 Legos is ultimately going to feel unrewarding. There's a line that one NPC's says on summoning that "if the being was on the size of [SPOILER], you might feel a little tug". Ok, that's a great bit of lore. I'd like a sanity/tempering meter, let me summon the Endwalker trials!
Also: mechanically speaking Searing Light gets really awkward when it desynchs with the Demi's. Can't use it during the demi so we have to either delay, loosing DPS, or just press on with the Demi anyway.
