Yes. We (and everyone else for that matter) still have Creation Magic. That is what summoning a Primal is. It's just that we have so little aether now as an individual that the aether for Creation Magic also has to come from somewhere else. Like aether crystals.

On a smaller scale, Arcanists are more then likely making use of Creation Magic to summon Carbuncles, Fairies and Egis. Arcanisim at its core is all about using math and geometry to shape aether into the same shape every single time. That's what all those diagrams in grimiores and codexes are. What seems to differ is what math/geometry the different summons are based off of. Carbuncles use the math/geometry of gemstones. Fairies are somehow created sentient beings that are housed in the various Scholar soul stones. Egis and Demis are based on the math/geometry of a defeated primal. Which is itself a product of creation magic.

For that matter, the Anima quest is also this. We literally end up making a sentient soul out of various forms of aether for the purpose of helping us in battle. The soul even compares itself to the primals as an example of what it needs to watch out for since it too is an aetherial creation created for one goal.

What seems to differ between Carbuncles, Fairies, Egis/Demis and the Anima when compared to Primals is the scale of the summoner/creator verses the scale of the created being. Carbuncles, Fairies, Egis and the Anima all have less aether then an individual person has. Primals have more aether then an individual person has. And it's when something created with Creation Magic has more aether then an individual does that the problems with Tempering seem to come into play most often.
