Can you just remove armor from the game, please?
It doesn't do anything, so just remove it from the game so people stop getting caught in the noob trap and stop building it.
... oh wait, you're goinna tell me it does something? Ha! Yeah, so tell me why, when I have 300 armor, Kha hits for 900 damage when, supposedly, I'm taking nearly 80% less damage? Oh and do tell me why an ADC with NO ARMOR PEN ITEMS can kill me in maybe 2 seconds at best if I build Randuin's, Thornmail, Tabi and all that?
So please, either give us the real armor formula (and update the in-game tooltip), or just remove the noob trap stat from the game.
