Ignoring Armor and Magic Resist (Last Whisper and Void Staff) has become over popular!
I am starting this discussion Because ever since season 4 has started, I have noticed that every one is building either Void Staff or Last Whisper (depending if they are AP or AD). I main tanks, and lately I have noticed that every one is building either of these items, making tanks useless. I understand that there needs to be a balance and a way to counter tanks, but there seems to be an over use and over powered feeling to these 2 items. What I would suggest is just reducing the percentage. By how much? Who can say, but would it be too much to ask for it to be reduced by 5%, its already at 35% (I think that's a little much). This causes the item to be a must have. Just play 3 games of league, I am sure you can observe and detect this pattern of over use.
"no I cant" but anyways yes that's what I am getting at. I didn't want to sound over zealous by straight out saying they are OP.
