Having no realistic options for defensive builds against them isn't fun. Shutting them down is essentially impossible because physical/magic/true damage says 'I'm always relevant!'. Hybrid magic/physical is bad enough. Why make it all 3?
pls stop
You're just in luck! I've got the solution to your hybrid damage/true damage problem right here!
It's called 
HEALTH!
It's the natural counter to both hybrid damage and true damage with only one champ being able to counter stacking this wonderful stat. And guess what, she's typically in bot lane, so not only can you get your build on well before seeing her. But by the time you do see her, your team should be ready to pop her like a zit the moment you lock her down!
well, why dont you build both mr and armor? I'm not sure how mixed damage is bad... have you been building 1 type of resistance all this time? I havent gone a game where I dont build both of em..
