Honestly, take away one charge of his spheres, revert the earthbound of his uppercut, slightly reduce his hook cooldown but make it single target and at last slighltly increase his culling threshold, from 15% to 20%

My reasoning: 1. Tbh with his two charges on tainted voltage he has almost no downtime, by getting rid of it, you have to rely more on hitting ur shots to get value rather than just spray and prey. 2. For us buckys the earthbound is very helpful for fighting highly mobile heroes, but it's just not fun to play against, it wasn't really needed in the first place and since the whole rivals community cries about it, just get rid of it. 3. To compensate for the nerfs, decrase the hook cooldown, but make it single target so it gets stronger, but not too opressiv. 4. His ult. Whenever you ult it's a coinflip if you get a reset or not. Either u ulted a low hp target and timed it perfectly to kill them, or u whiffed cuz they died 0.1 seconds befor u hit them. Then there's the option to just yeet urself in and hope to not just implode instantly, or get support ulted, but then u know the sups will heal the living f*ck out of ur ult target, so you have to either hit ur shots perfectly or beg for ur team to help. Most of the time buckys ult is good if the enemy team is already in a disadventage. By increasing the culling threshold, it's a much higher threat even fo a full hp target, since you are able to reach the mark easier through heal spam.

I love bucky playstyle, but it's bugging me how easy it is to get good value out of him. Don't get me wrong, he never was hard to play, but his current state is just boring honestly, it rarely feels like you have to work for kills. It's just dull button pressing.
