Klaw Swipe being an overhead would be pleasant, but not essential. Same goes for damage--dealing a truckload for no meter would be good, obviously, but I wouldn't want Reptile going down that road. Reptile's this close to being perfect in his little corner of MKX, and it wouldn't take much to make him more complete without going overboard.
His normals are solid and his neutral's pretty sharp, so having Forceballs that aren't so risky would be a plus. That or just making the EX ones really silly, if only to justify their inclusion. Stopping Forceballs is cool, but it's difficult in practice. Compared to dash cancelling or delaying, it seems slow and expensive for what it gives.
Elbow Dash being combo punishable on block is something I have mixed feelings about, but I can understand the reasoning. That said, for its intended use as a fast punish (and for mobility, and left/right shenanigans), the damage/knockdown gained versus what you receive if you mess up is nerve-wracking. The EX version starts combos like EX Klaw Swipe, yet is more unsafe and doesn't have armor. It seems kind of short-changed (to be fair, it has uses). The pre-release ED was a frame faster, right? Around the same speed as EX slide? That would have made for a less meter-intensive punish at those frames, if it were.
I use Klaw Pounce in combos all the time, so I won't say it's useless--rather, it's head-scratching as an overhead. Easy enough to react to (moreso the farther away it gets), and minus infinity on block. The EX version can spit in the face of some zoning and gets okay damage, but at zoning range its properties as an overhead are questionable and its safety is still the stuff of nightmares. I would honestly be totally fine with turning this move into a mid if it meant it could be safer on block or something.
I don't see the use of meterless Klaw Swipe. It's not safe, gives a meager return, and Klaw Pounce works fine in its stead for combos. Having it be safe on block would give Reptile a way to build meter from his useful hit-confirmable strings (while still leaving him at disadvantage). EX staying unsafe would make sense, given it's a reasonably fast combo-starting armored mid. Being an overhead would be gravy.
Having any (or all) of those would go a long way. In short, I could see him being reverted to a pre-release Reptile with a safe meterless Swipe and a safer Pounce.
