Yasuo's Knockup, Teemo's Mushrooms, Karma's Ult, and a bunch of random crap

the Knockup for Yasuo when performed under a turret (with him in range of the turret) doesn't seem to trigger turret aggro, is this on purpose? Is it because the knock up in and of itself doesn't do damage? Is it something that should cause turret aggro considering it's a requirement for his Ult? I'm not positive if it was meant to be this way or if it was a bug, or just a random thing i ran into.

Is there no limit to the frustration that is Teemo? It seems to me that the mushrooms for Teemo are unlimited and tilting to me personally, I swear I think i have a mushroom locator somewhere in my mouse that allows me to run my champ over every single mushroom ever placed on any map. While I do see the need for Teemo's mushrooms I think that they should be limited in the same fashion that Zyra's seedlings are. Max 8. with a relatively short timer. A map should not be covered in mushrooms that are for the most part undetectable and do as much damage as they do. Half of a casters life on one mushroom seems a bit excessive. I have come to the conclusion that the CEO for Riot plays Teemo and that's why he gets buffed every single season, it's the CEO wanting to play the game in god mode. While it may feed his ego it's a broken champ that needs to be seriously scaled back.

Someone explained to me the concept behind this next one but I'm kinda slow so here it is again... I'm on Twisted Fate, I see the card leave my hand and start thru the air, only to have the target run into the bush, now we didn't have vision in the bush but the card is already on it's way and should hit it's target, instead, it just POOF disappears. Yet there are instances of other champs doing the same motion that when I disappear into the bushes the 'skill shot' still lands.

Why is the 'grab box' for Blitz's alternative skins SOOOOOOOOOO broken?? I've watched games that were recorded, slowed down and the grab isn't even close, yet it's still managing to pull the target???

On the Topic of Yasuo... I hate your wind shield, like REALLY FREAKING HATE IT! and Kalista stop jumping around like a mother frickin mexican jumping bean! it's annoying!

Tenticals... enough said

finally, has anyone else run into this? When I play karma, there are times i'm hitting Ult then Q but for whatever reason the Ult portion isn't registering and it's firing a normal Q. Maybe I'm fat fingering it or missing it but it happens quite often.
