Not sure if trolling or not… But alright, let’s do it.
You are taking this suffix too literally.
You say that because it’s been used everywhere, it doesn’t mean that this is right ? Well, I do agree with this, literally speaking, what you say make sense.
But commonly speaking, I find Pyromancer > Pyrokinetic. I bet my 2 cent everyone here is thinking the same way, and I’m sorry for this OP… Because this is the first term that come in mind for a Fire Magician (it may differ of course…).
Plus, -mancer is more than that, rather than just divination using Fire for Pyromancer and so on for each type, it means that you mastered the associated art at a point you can even “read” it (I’m surprising myself for writing this, but I don’t really care lel).
In this case, a Cryomancer doesn’t mean “Reading the futur using Ice”, a ToS “Cryomancer” ain’t doing this AT ALL xD.
It means that a Cryomancer is a master in the art of CREATING ice and frost.
“Creating” is important too.
A Pyrokinetics would mean that you need to bring your own torch to fight. Not cool bro ! I want my gigantic fire pillar to burn down to ashes my ennemies ! And it lead us to my last point : the DIVINE part.
-kinesist means that you manipulate the associated matter, not creating it, and the fact of creating something from nowhere is the most important part. It’s the real “heavenly” part of the term -mancer imo.
That’s not convincing at all I know, but there is too much sense to lose and not much to win using “-kinetic”. Yes it’s not right. But your solution isn’t worth either.
PS : It’s by inventing terms that a you make progresses in a language. Perhaps, maybe it’s time to move on and change the definition. As far as I know, nobody use this -mancer in a way implying Divination.
