Can we please do something about Armor and Magic pen?
As someone who tries to go Tank and build armor or magic resist, its hard to stay alive after the "changes" back in season 5. Its not that it shouldn't be in here, but its gotten really hard to do much when an enemy mage (or AP assassin) can get 3 items and penetrate 65% of my MR with every spell.
Example:
I just went Galio, and since you guys at Riot pretty much got rid of all mana pots and the mana regen spell, I knew that after you guys at Riot (not nerfed) slaughtered the MR items, that Galio would at least need something to help with these issues. 
And it bewilders me that there isn't a way to gain a ability like Kassadin's passive gives, but for Tanks on some Tank item that doesn't benefit AD or AP champs. A way to block 10% of the enemies AD or AP or something. With all the armor pen and magic pen, can't there be one item for damage reduction?
Idk mate, mundo and malphite seem hard enough to kill as is. Scroll through the items, bro. I rarely use the complete recommended set, it's just not flexible enough to be used in every game.
