I kinda wonder how these revelations play into Fray and Myste from the dark knight job quests. Especially with Myste, who would seem to be a summon who can create more summons, like a primal creating adds to fight for them.
Just a personal theory but I think it has to do with us being sundered, of course, amount of aether is an important matter as well but during the Amaroth questline, we were tasked with weaving an item into existence, not only did we need to gather aether, but npc also mentioned how it felt like we were imcapable of mentally casting the magic.

I think that is why summoner summons aren't indefinate. We are using a less perfected version of creation magics, downed from primal summoning which ascians taught beast tribes to sow chaos and imbalance of aether. (Hence primals feeding on aether constantly)

My theory is that is exactly why summoner needs runes and symbols to guide their magics, or the combine faith of a whole group. It is because we do not have the mental understanding and instinct to weave such interacate rules for aether purely within our minds.

Essentially our creations 'leak' aether and cannot hold a stable form without constant feed, unlike I imagine proper creation magic where creations are alive and well far after their creation.

We have even seen spriggans being created, a race of monsters that had far outlasted the race of ancients who created them. Cleary ancients creations do not require a constant feed of aether.
