First of all, we don't know whats really happening here.
Im guessing from the footage I've seen, which is very little, that there will be a universal nerf to launching armour. Or a basic rule of:
1. Any attacks that previously launched for a combo won't have armour anymore, so they will be straight up fast launchers (like War God's overhead sword) but they will have different properties, like hitting overhead or low, so they can be used in mix ups and offence specifically.
2. Any attacks that have armour will no longer launch for a combo, but they may have other properties, like being completely safe on block, or are command grabs, or have pushback etc.
So in the case of Reptile, his MB claw launched, but didn't have armour, while his MB flip has armour but splatted the opponent.
I can't see this change being character specific, but it could be a universal cast mechanic, and the sad thing is, it will be the only one thing the cast will have as a common rule, and it may all just be too late.
Im also sure characters have been packing armour on almost every move will get something in their design to compensate.
For instance, if Tempest no longer has armour on his MB spin, I'm sure it will just be fast as balls, like 4 frames or something, which means it will function like MK9.
