Yep, I know that (cf. the links). I have even separated them into two classes. (as well as the Omega level telekinesists, healers (well, there is only one and he is also an Omega class or level mutant) and Earthquakes Production (an alternate Moses Magnum, not a mutant as far as I know, even on that world). The only thing I haven't done yet is dividing Level from Class, althought some says (without references of course) one of those is relative to the power level potential and the other to the achieved/trained level power. As far, I don't believe that, as it was from a guy who stopped the discussion as soon as I asked for a reference to check.
I'm interested by that one, and you seems pretty sure of yourself ; Have you found a reference I've missed ? (I've missed a lot of issues those past few weeks)
I have only the (controversial) interview of Remender during his Uncanny X-Force run where he stated she was an Omega Level Mutant. It was controversial partly because he was comparing her to Jean and Prof X, both telepaths, and some argued that Remender intended to say Omega Level telepath, but:
-She can be an Omega Level Mutant because of telepathic power (combined to telekinesis furthermore).
-Remender said Omega Level Mutant, not,Omega Level Telepath
-I won't argue if this is canon (which is not), semi-canon (which is the best deal), or irrelevant (which I find too radical).
And I forgot (for those who wouldn't find the way to move to the "top category":
