First, I appreciate this thread and the tag. Regardless of ones opinions on the matter, making a buff or nerf thread on TYM takes balls and I commend you on yours.
Second, thank you for the tag.
Third, sadly, I cannot entirely agree with most of what you proposed.
Now, 114, yes. Numerous times yes. That, to me, is a 'fix' not a buff so doesn't fall in the same category. I can certainly live with it not working, but it SHOULD work. Making it work properly wont push him up or down in strength, my opinion is that NRS needs a comprehensive sweep to find and fix ALL of this crap across all characters. I don't care of Lao has whiffing issues. If he does, fix 'em.
Choose your side on ChokeAFool would be super nice, but it might end up being too strong and if it became a triple input move, I would hate my MKX playing life. If it WERE changed, and I'm not real sure it should be - Id like the command to remain the same, but you hold the direction of the throw/slam. So, done like any distance-alterable move, you'd just db2 then hold back to chuck them behind you or forward to throw them in front. Something like that. Performing the move without an additional input (just db2) would make it react exactly as it does now.
More frames after Air Grab? As a pure luxury buff - I can see it being nice. Its not game changing, but I could see it.
The rest though.. I dunno. I see Kotal as a very variation specific character. He, more-so than many other characters, benefits enormously from being able to use all his variations. I say that because I feel like Kotal is very solid and instead of trying to fill up the holes that an already strong variation has, I'd rather switch to a different variation to make the MU work. I know you're not advocating buffs to make any variation totally stand-alone, but I'm speaking from a general standpoint on how I approach Kotal from a balance perspective.
I think Kotal is strong. Top tier? No.. but hes not far outside of them. I feel like he's knocking at the door, when you talk about him across all his variations. He certainly doesn't have the dirt that some of the top guys and gals have, but he's solid and across all his variations, its hard to find *too* many MU's that you cant put to around a 5/5.
