A kit like shyvanas is so dated its just going to get worse and worse
No built in cc other than a 150 unit 'shove' on her ult.
Not even a slow.
She does damage with some on-hit items but on-hit items suck for melee champions, riot made sure of that when they removed devourer and reworked rageblade.
Somehow being able to do damage when building damage items and auto attacking someone on a melee champion was unhealthy.
Meanwhile vayne two-shots from range with a 2 sec cd reposition stealth ability and a stun and that is healthy..
Yea really not sure what riot was thinking with this shyv rework... It was clearly not intended to make her any more playable in diamond+, she just gets kited if shes ahead and rendered useless, or she's behind and then is useless regardless of what the enemy team does.
I'm telling you now the ONLY way shyv will ever be good is if she can either: abuse her ability to clear the jungle quickly and transition that into a powerspike, or she will have to be given utility. Given that devourer is gone and never coming back, case 1 will never happen again. Given that riot seems averse to giving shyv utility, case 2 is also impossible, which means shyvana will always be a terrible pick.
Simplest fix would just be to make her ult carry enemies AND allies the full distance of her flight. Would mean that you can makes plays and would make her a cool pick in competitive with a special niche. She can flank and own people by clumping them all together and delivering them to her team, or she can lead her teams escape over a wall for example.
The fact that this hasn't even been tested and checked to see if it would be a healthy change really upsets me. Would make shyvana not only less binary, but more competitive and would give her a niche that she doesn't have anymore. Clearing the jungle fast isn't a niche anymore its just a necessity.
