MR items

Hello Riot, I'm a big fan of Nasus, I think he is really fun to play, and very god at dropping some disreespect on 3v1 xD Anyway, the only thing that I do not like is......having an enemy Orianna fed 14/2....and no ways to counter it.

In game, you can build a hell lot of armor, go up to 250 easily... But the Magic Resist --' Even with Banshee + Spirit Visage, I don't even go above the 150 MR....

Wtf? AP mage have the biggest DPS in game, and you can buy no defence against it.... Is that called "balance"? Come on, stop trying to nerf them, and make them look ridiculous (and crashing your reputation for "best balanced game ever"), just give us NEW ITEMS to COUNTER THEM.

Is it normal that an Orianna, or a LB 3 shots me? While on the other side the adc just shikles me? You say "ADCs build armor pen. to BRST them down", my god how foolish?

Anyway, please do something, its not even enjoyable anymore :(

But keep up the good work :D
