Sure you can toss on your ults to provide more damage but also they have no ways of mitigating damage what-so-ever and the escapes they have are sub par compared to what Yi can do when he goes AP.
Another issue: AP Yi does only need two dolans and a pair of boots to completely decimate typical AP lane carries. Combined with the fact his main damage is not a skill shot makes those ratios seem huge. By all means a Lux should counter Yi as she has a decent CC and survivability, but even she with a few dolans cannot match the ratio AP Yi has.
Another point: Take LeBlanc who, the entire community has agreed on, has a decent early game, and yet falls off hard late game. Ala Yi. Well her Q and R combo is what makes her so feared early game and yet Yi can easily pump out far more damage and laugh at her Q and R combo.
So why should a melee AD carry who is, for the most part, meant to be an AD carry allowed to have such huge ratios when he can be so versatile? He can lane, he can jungle, he can do AD or AP and even be tanky, and yet his AP ratios are so high.
Basically the main thing is why is his ratio so high on his Q and on his heal when other AP mages have lower AP values, and less survivability and less versatility? That's what I'm wondering.
Exactly, he's basically GOD in lane against pretty much any other mid, and personally as one who plays mid a lot, there is no champion that I find it harder to lane against, pretty much any other mid i can poke and harass effectively, and those few that I can't, I still have a good chance to beat or at least match the enemy's creep score by just playing passively and farming against them. Yi on the other hand, makes me play passively, buy defense AND sustain items, and gets to free farm anyway, while I'm still lucky if he doesn't zone me out so hard he can just take away 1/3-1/2 my farm.
Yi's alpha strike is not ignorable during laning phase no matter how much you stack resistance or life.. (unless maybe you rush like a FoN or Warmogs or something or already have very good MR innately or from an ability...) he hits you with it constantly and automatically, and you can't trade back with him effectively since he can laugh at your damage and cooldowns with meditate. You can't even chip him down after he blows meditate to make him back off, since there is a good chance as a cooldown-dependent champ that you won't be able to do enough poke damage before he gets meditate back up.
Personally, I think the best way to deal with Yi during the laning phase is to get a lot of ganks on him or just switch places with your AD carry or bruiser... any AD carry, ranged or melee, and most bruisers, will be able to put out enough sustained damage to force him to back off, and will have no problem farming against him and zoning him away from the creeps. And he won't be able to follow you, because in a double lane he can't farm and can be focused very easily, and on top solo, he will at LEAST be forced to start buying wards or he's gank meat (he should get ganked in mid too, since he always pushes, but the top lane is a lot longer, and it's closer to buff objectives where the jungler tends to be)...
