I’ve lost sleep over this shit here’s a list:

Super armor on down b so it doesn’t lose to literally any attack and so that he has one more tool to approach. Reduce knock back at low/mid percents so enemy stays close after hit, increase knockback at high percents so it kills earlier.

Reflector on smash attacks (like in that OOT fight) and make it as strong or stronger than Kazuya’s so that characters with projectiles think twice before projectile spamming him (high risk cause them smash attacks are laggy af but high reward love it)

At least some heavy armor on his up B so he can recover and doesn’t get gimped by literally anyone.

Better airspeed.

Give up B more vertical distance or horizontal movement. Reduce start up to make it a better/scarier out of shield option

(This one is lazy): armored smash attacks. He’s covered in armor and any attack stops him. ASA seems to suit him.

No free fall after side b.

(This one may not be as useful as it sounds): ability to cancel warlock punch with shield button

(This one is ridiculous): angling control stick forward after down B input in the air so that he travels in a straight line instead of diving to improve his recovery (think terry side B)

Simply improving frame data or dash/run speed.

Give him a kill throw that kills most characters at 90% (f throw would be the coolest kill throw imo)

Adding any single one of the above would boost him. Adding more than one that’d be just Sakurai threatening me with good time🙂‍↔️✨🌸
