You're going overboard with this "Revan pushed Vitiate hard" thing. Vitiate was pushed to the point where he had to unleash his full power, but when that happened, Revan stood no chance.
Literally, the fight is Revan getting hurled back by Vitiate's TK, then Vitiate uses the opportunity to attempt Mind Control. Since Revan has already learned how to counter it, he uses his "Force in Balance" technique to throw the unprepared Vitiate backwards (that would happen here as well - fair enough). After that, Vitiate sends a few casual bolts at Revan that Revan ducks, blocks and deflects - sending Vitiate further back.
After that, Vitiate decides to go all-out and charges up his Lightning Storm. Revan tries to contain it and failed so utterly that one might well call it a stomp then and there.
So as I said, Revan wasn't stomped in the overall fight, but he was stomped at the end when Vitiate unleashed all of his might.

My point is that if Vitiate (even if it's Pre-Nathema) unleashed all of his might here as well, Revan wouldn't be easily discarding it like you're suggesting 😬
Obviously anything less from Pre-Nathema Vitiate would fail utterly. And I already gave Revan the win.
