How to effectively take care of the Master Yi + Kayle issue

TL;DR: either nerf Ardent Censer by enabling the passive on SHIELDS and SHIELDS ONLY (or just make it not synergize with Kayle's w)

• Other options include removing Censer's level-scaling on-hit magic damage. (remember; Kayle and Yi are both gaining 'solo lane' and 'solo jungle' EXP for the majority of the early game, so will typically gain levels faster than other people at this time in the game. Therefore, they'll reach Censer's damage level spikes a lot faster than other champions on the rift are reaching their spikes. This is super aids at lvl 6 and mid-game!)

• Making Censer more expensive

• Giving Censer's passive a cool down period

• Ban Yi every time you queue up for a solo game or risk losing because of a single item

Thanks for reading my TL;DR.

Now for the real beefy part of this post - explaining why it's so unbalanced (if it's not already obvious enough)

Whether you've played against it or not, you may have seen footage and/or heard of a "strategy" whereby a Kayle, usually situated in a solo lane (normally top) heavily itemizes allied-champion-buffing support items such as Ardent Censer, Knight's Vow, the new Zeke's, etc. and plays alongside a Master Yi jungle.

I would like to stress at this point that it does not necessarily matter whether or not Kayle loses her laning phase because she can quite comfortably farm until Censer. Once she has her Censer, (it's basically game over by this point anyway regardless) she's at little risk of being punished after level 6 because of her incredibly forgiving, mana-less ultimate; and she fears no aggression from her enemies because of the -inevitable- constant presence of her Master Yi in the top side of the map.

Let me break it down to you like this: this item (Censer) is simply not healthy. I'd like to learn from anybody who can effectively counter Kayle + Censer + Yi with the coordination of a solo queue team.

Ardent Censer Kayle healing Master Yi literally whenever her W is off cooldown, is not only obviously healing him; but it's also giving him a movespeed steroid (two very important things for a Master Yi who wants to 2v5), and if that wasn't already enough, it's also constantly granting him attack speed from the Censer passive! Oh yeah, did I mention that Ardent Censer also grants level-scaling on-hit magic damage as well as the aforementioned level-scaling attack speed steroid? Wait, did I mention that it also increases the Kayle's healing by 10%? Oh wait, I did? Sorry about that

Ardent Censer is almost 170% gold efficient whenever an ally is buffed by its passive. Great, right? ...considering it only costs 2300 Gold. Therefore, we're talking about 11-13 minutes for an average-CS Kayle to first-buy this item. Now let's add constant pressure from Master Yi to the mix, and give a kill or two to a poor-CS Kayle. If she didn't have her censer finished, she does now!

Cutting a long story short, the game is won by the Kayle and Yi split pushing top. It is often not possible to counter this given the typically poor communication in solo queue games. Ardent Censer is the issue, as it is completely pointless trying to fight Yi once Kayle has finished her censer.

Making an attempt to collapse on the two of them is pointless because she gives a ridiculous amount of free stats to her pet Yi (who will disappear from the map every 5 seconds, effortlessly avoiding your hard CC abilities with his Alpha Strike, whilst not being as conventionally 'squishy' as your average Yi, because Kayle can simply ult him + offer him kiting potential & heals every 5 seconds)

If Kayle's Yi isn't present and you see the opportunity to make a pick, she can just ult herself and hope to utilize the convenient tanky stats of her Knight's Vow to survive ganks as well as the healing buff on her Ardent Censer to further avoid dying in general. Her heal also makes her run (fly?) away from these situations faster as well, conveniently for her.

If Yi's Kayle isn't present, good luck collapsing on him and his 18 kills @ 20 minutes. That's all I'm gonna say.

Thank you, and goodnight.
