True damage on Yasuo feels kind of frustrating

Hey,

So this isn't really a "Yasuo most broken champ in the game"-post. But I've just been playing a game as Mundo with about 240 armor and the enemy Yasuo got kinda fed early. When I fought him, he always dealt more true damage than anything else to me, which really feels bad for somebody building kinda tanky items, playing against a champ without a single drop of true damage in his own kit. Especially when you consider his ults armor penetration and other items like . I see a lot of useless Yasuo's so the champ itself isn't even my problem. My problem is, when he's not useless, I honestly don't know why I still should build any armor besides , because these are the only ones really giving me some kind of reliable damage reduction. It just feels crazy bad to build armor against champs that are not Master Yi or other champs with inbuilt true damage and then seeing that most of the damage they dealt to you is true damage + all the ways to ignore or reduce parts of your armor.

Of course I don't die as fast as the other members of my team, but seeing the way I died makes it so much more frustrating than just seeing "Ah, he's crazy fed, has armor pen and maybe someone else built BC.".
