Tanks?

So I and a lot of other players in the game feels that tanks are too overbuffed in this game when it comes to items and I feel that this is an issue. The inevitable point in which tanks are too fucking tanky that an adc that can't dish out consistent true damage, like vayne, struggle against them. Tank items are much cheaper than adc items and mage items. Does anyone feel the struggle going against 2-3 tanks in a game of aram/rift? You can't do damage to them without them going all up against your face only to kill you before you get in those last few spells/autos, and it's extremely frustrating. Not only that, the point in which they scale up is uncanny to adc's or mages. even if a tank feeds, give him enough time and farm, he'll be doing a tremendous amount of damage while still tanking through a stormy team fight no matter what when compared to mages or adcs who, if unable to keep up with the game and scale, they don't do damage. There's a lot of holes in this paragraph but this has just been my experience in the game, riot hasn't done anything to fix this, tanks should be tanks but the tools riot gave up hasn't done much to help, void staff and last whisper can only do so much when the tank is chunking away health and you're only chipping their's away.

So bottom line here is, either nerf the tank items or give the squishies other items to combat against tanks better.
