Can we have a patch dedicated to fixing old spaghetti code?

There are so many interactions in this game that make absolutely no sense. When you ask why you get more or less the same "that's just how it is" answer

You have champs like completely ignore hard CC with his blink. As long as he pressed E just before the CC lands he can ignore stuns, roots, knock ups, etc. It feels so bad every time I see Ezreal get hit by a blitz hook just to blink away anyway. Trist is similar to a degree but it depends on what frame of her animation you hit her on. On the flip side you have a champ like Aatrox that is supposed to finish his jump but gets knocked out anyway if someone sneezes near him.

You have autos follow you even if you leave the range. Both for ranged and melee. Rengar pops his ult and leaps at you. You instantly flash over a wall. Rengar lands where you were and you eat the leap damage and Duskblade proc and die. WUT? "That's just how it is". Cait shoots an auto at me right as I finish my back. I get back to base, buy, and start running just to get popped with a crit from Cait who is literally in her base. WUT? You're running away. The enemy Morde flashes on you to finish you off. You instantly flash away. His auto goes off anyway. Copy paste this for a ton of others things like Darius ult, Garen ult, Syndra ult, etc "He/she started the animation though. That's just how it works".

Wards still give vision for a second or two after being destroyed. Wut?

Lee Sin can R flash you but you can't flash during his R. Wut?

Tryndamere's W can proc electrocute. Not making this up. Lol WUT?

You're playing against Soraka with . She is healing her team during a fight. This doesn't put her in combat though and she continues to receive the Warmog regen while spamming out heals. WUT?

.......WUT?

presses R and dies. Her corpse continues to cast the full duration of her ult. WUT?

randomly loses axes for absolutely no reason but especially after taking a Thresh lantern. WUT?

E>Q's away anyway after eating hard CC. WUT?

counterstrike buff doesn't activate for .25 seconds

still blinks in her shroud despite getting hit by hard CC. WUT?

I WAS IN ALPHA

Memes aside, I could make a list that is ridiculously long. Just take a look at the comments that are bound to point out dozens more. Can we get a patch to fix all these interactions that make no sense? I'm tired of hearing "that's just how it is". Everyone knows these interactions make no sense. Why should we just accept them because Riot hasn't fixed them?
