He is my 2nd most played jungler and I have noticed that, as I try time my alpha strike to dodge skillshots and CC's, some of the time it would not work and that yi would still be able to take damage from it, now Im not saying this happens all the time, im saying this happens some of the time, that I have watched streamers play him and I myself that played him
Maple Crusader2 votesYi still takes damage from targeted DOT
TehNACHO2 votesWatch the video; that's not the problem.
Yi takes damage from non-DOT abilities like Ahri Charms and Riven Ults, and also has the same problem Garen has whenever his ultimate is bugged; if the enemy breaks line of sight while Yi's in his windup animation, he'll blink for an instant but won't follow the enemy through.
Sauceyapples1 votesSome of these examples in the video are bad, when he says, "I WAS IN ALPHA," but you can clearly see that he wasn't, or he'll say "I WAS IN ALPHA," and it's not even on cooldown. However, that being said, there are a couple of times where he would go into alpha, and would still take damage from nothing, like 
's ult. In that case, I think he did have red buff on him, but it didn't look like he was low enough for it to tick enough damage to kill him.
TehNACHO1 votesI play(ed) Mid Lane Yi so I can see all 3 stages of Alpha Strike, yeah a few of them just clip him in the windup stage.
Red buff would not deal 20% of your health in the fraction of a second that a chain 2 or 3 Alpha Strike would take~
I should note however Alpha Strike does entirely cancel, not even go on cooldown, depending on what happens during the windup animation. The most common issue is breaking line of sight.
Sauceyapples1 votesWell if it happens in wind up, then it's not really in Alpha then right? Kinda like how 
can still get cc'd in the middle of his q, canceling the ability all together. Granted, that is a really long wind up, and he's not turning invisible, but the point remains valid, I'd think.
TehNACHO2 votesThe difference is that Sion's is a windup that under normal conditions is supposed to be cancelable.
An example of a champion with a slow but should be un-cancelable windup is Garen. And I was here when the forums bitched and cried over how it was a horrendous bug with Garen and how Riot tried to fix the bug entirely. That sort of treatment should extend to Yi.
Sauceyapples1 votesTrue. How I feel about the ability though is still valid, Yi should be able to be hit by AoE's while in Alpha Strike. He's still there, just not visible. Thresh hook is maybe something different since it's one target and clearly you wouldn't be able to hook something that fast, but for example: If an enemy Kennen ults, and Yi alpha strikes targets that are in that slicing maelstrom, he should be hit by it. He's still there, just not visible. If a Teemo gets hit by a skill shot while invisible, he still takes damage right?
Jalkan2 votesThe skill description clearly states that he becomes untargetable, similar to how Fizz can't take any damage during his E.
Sauceyapples1 votesI guess. I just think there should be some draw back to it, Yi mid to late game is already a monster enough as it is. At least with Fizz his E's CD doesn't shorten based on how many aa's he does. 14s minus 1 auto every second, which is pretty slow for Yi considering he scales off crit and attack speed, gives him an 7s cd on alpha strike and that's without CD reduction. In some late game instance's, i can't confirm this, it feels more like 3s. So if we do the math 14s at max with 10% CD reduction from 
is 1 and a half seconds ish, so that's 12.6. That's not including if he has runes (assuming he doesn't). so 6 autos over 6s (which again would be slow for him) would be enough to make it a 6s cd. That is already lower than Fizz's E which is 8s at max level, plus 10% cd would be 7.2. So essentially you're making someone invincible for probably 1/4 (assuming his alpha strike takes 1 second on a three chain and that he's doing 2 aa per second which is pretty reasonable) of the time if he's aa'ing the entire time, plus on top of that a true damage for 5s with E, and my math is also without Yi's passive. Yet, of all the champions, people all of a sudden get mad once he's untargetable because he dies. In other words, if you are complaining that you aren't untargetable for a quarter of the time that you're in the fight, while probably doing the most damage on your team then something is wrong here. Fizz is mostly one and done sometimes can go more if he has 40% cd reduction, which is doubtful, however, because all of the ap items that give you CD reduction don't really give that burst damage that Fizz needs, other than lich bane. I'm just saying. Sorry for the long speech, it probably has holes in it because I'm not the best at math, and I was confusing myself in the argument at some points xD.

Not untargetable
Sauceyapples1 votesTL;DR allowing Yi to become partially targetable during Alpha Strike allows for more of a skilled player to play Yi, meaning you'd have to choose when you alpha strike. I'm not saying EVERY ability, just certain AoE's.
Jalkan1 votesSkilled Yi players do choose when they Alpha Strike. See in the Cowsep video, he uses it to avoid high damage burst spells. Unskilled Yi's who jump in simply get CC'ed and bursted.
Sauceyapples1 votesto me it looks like he's using it when it comes off cd and it just happens to be in line with high damage spells. Look regardless, I do see your point in that respect, but I don't agree with it.
Jalkan1 votesThere are many parts in that video where his Q was off cooldown and he was saving it for a burst or CC.
Here's a different video from over a year ago of him dodging spells with Alpha Strike: https://www.youtube.com/watch?v=rx5u7i_XT7g
Sauceyapples1 votesYet again, in SOME cases he's using it to dodge. That first penta kill he used it immediately after it came off cd, he also used it several times immediately after cd in different ones too, not just to dodge anything. I see in SOME cases he does, but in most cases it looks like he's using it just off cd. Besides, the point wasn't why they were using it, it was how much. The zed dodge was pretty sick though, i'll give him that. Plus again, it's still on a three second cd in these, too, and with no draw back. It's just making my point. He's making pentakills ALONE. NO ONE ELSE. Him against 5 people. And this is OK with the league community?
Jalkan1 votesYes, sometimes he uses them just for the jump, because in those cases it's just a good idea, but at many other places unskilled Yi players would have died. The bug is going to be fixed because as others have said, it's a core part of his defensive ability.
Sauceyapples1 votesAlso, I said I don't think it would have killed him, the red buff or the ignite.
Pentarina Only2 votesRiot seriously needs to fix this. I stopped playing Yi because of this bug.
Post this in Report A Bug too.
