Master Yi + Sated Devourer + BotRK + Wit's End + Last Whisper

This is just OP.

I don't care what anyone says, this is insane attack speed, every attack does 16% of target's current health + 125 to 179 physical damage + 214 magic damage(Devourer now only goes to 65 magic damage right?), and every 3rd attack does 32% of the target's current health + 85 to 139 physical damage + 428 magic damage.

I don't even need to write specifics and I'm not going to, because anyone who says this isn't OP is crazy.

"Oh but you have to get 30 stacks first" Oh but its also a get-out-of-jail-free-card Even if you're down 0-100 and have no towers, once a Master Yi gets this he can fucking solo carry by 2-3 shotting everyone who comes in his way, tanks included, within seconds due to his crazy-ass attack speed and passive.

Have a jungle Master Yi on the enemy team? Is he building like this? Well say goodbye to your tushies unless you can end before he gets this build because then he's fucking unstoppable. Oh, not to mention any defense he might have, which he still has room for two more items. So, say, against an MR team, Spirit Visage, against an AD team, Randuin's Omen, and no matter what just grab a Guardian Angel and you'll be unbeatable. They got a lot of CC? Replace Spirit Visage or Randuin's with a Mercurial Scimitar, its just that much more damage and you can remove all CC affects currently on you. Heck, if they aren't building armor you can just build it in place of Last Whisper.

I really can't imagine anyone defending this. I mean really, 16% of the target's current health plus all that extra several hundred damage in both forms of physical and a bit of magic so armor doesn't affect it, every some 0.5 seconds at only 1 attack speed, and with all this AS it'll probably be about 2 so one of these about every 0.25 seconds, and every 3rd hit deals 32% and all that extra magic damage x2, plus the extra physical damage x2, and whammo.

"Oh but you can build Thornmail" Oh but you can do that for almost any AD champ. And I don't think Thornmail actually affects the BotRK passive since it isn't actual AD and is just an on-hit effect, so its basically returning some 37 to 53 damage back to him every hit and giving them 100 armor, only 65 with the Last Whisper, even less with other armor pens such as runes and masteries, plus there's the magic damage from Wit's End and Devourer that isn't affected by it.
