Kayn bugs for christ sake

It has been almost 3 years now. THREE years Why the hell does kayn still have SO MANY BUGS. Here's a small list of what happened in a singular fucking game.

1. w slow applies maybe 2/3 hits ( no they weren't misses. they dealt damage)
2. rhaast knock up not applying but dealing damage. likely same bug as above.
3. there is a bug WHERE YOU LITERALLY CANT CAST YOUR FUCKING ULT. THIS ISNT EVEN A RARE OCCURRENCE.
4. one of my favorites. there is a bug where turrets/heimer turret will continue firing at you in your ult. dealing damage and all
5. voli gives ranged orbs. yeah. a CLEARLY melee champion gives range orbs.......

This is just one game. with multiple bugs that could easily cost an entire game. these arent recent bugs either. these have ALWAYS fucking been there.

i know kayn isnt a popular pick, but that isnt an excuse to leave him so rampantly bugged out his ass.
