Item suggestion that could fix ADC issue.
I wanted to post this in gameplay too because I really do think this item could solve the ADC issue we have right now. The huge issue with ADCs right now is that the crit their doing is too bursty - especially on assassins and mages. They're able to do this all whilst being able to build a lot of defense such as 
. So here's my concept of an item that could solve the issue we're having.
+70AP +30 Armor +30% Attack Speed
UNIQUE: Autoattacking an enemy champion 2 times increases your Armor by 10, your AS by 35%, and gives you 15% crit reduction for the next 10 seconds (35 second cooldown)
Price: 2900

Too often people are complaining about their ADC's losing lane & it's affecting everyone else. This is a situational item that can be build on AP assassins and mages, in situations where the enemy ADC is too disruptive. As of now, the only protection Mages have from ADC's is zhonyas, which is useless when fighting with an adc that can do 400dmg in a single auto.
As an AP assassin main myself, I know the pain of being killed by 2 vayne auto's myself. It's not healthy, and the only reason ADCs are OP is because the classes that counter them (Mages and assassins) are being out-bursted by adcs themselves...
