Can you please start fixing those Sion bugs. There are too many of them. Come on RIOT

From the very first moment Sion got reworked. bug don't stop showing on him. And there are a lot of them. Q being canceled while charging with no reason and so into full cooldown. Ult being interrupted by Stuns at the beginning of the channel and make Sion stop ulting immediately. Q does not hit albeit the enemy champion was inside it. E shoot minions in a wrong path. E Minion shot doesn't damage or slow targets. E on minion kills it without making it travel. You cannot watch a place on the map by marking it with the cursor while charging Q. Q sometimes slow and not stun even after 1 second if channeling while your ms is below 275. Ult bounce of of terrain created by champions. and many many more. But no fix to any of those even after 4 years Riot, please do something about it.
