I can agree with most of this, but that exact reasoning is why i think he'll be "good but not great".
That teleport looks hella unsafe, and not having at least the "threat" of an OH normal up front hurts. For example, I would say Kitana would take a significant hit without her OH, and it doesn't even launch and is kinda slow. Not having that makes him a pure zoning/space control character in a game that doesn't reward such types of characters. Cyber Kano 2.0 looking character. Cyrax and Smoke look like they would take his lunch money in a 1 vs 1 MU.
Though one thing I'll admit, the EX Flame is gonna be a life vest against the pressure characters. It's something some of those types characters don't have that they could use/need. It's actually better than unsafe launching armor imo for this type of character.
