Adc is too strong

I know this has been circle jerked a ton but seriously though adcs are so fucking annoying and they have been since they got their "special class update" late 2015. I don't even know what to do with them now besides give a big ass overhaul to adc and support items. Get rid of fleet footwork and legend: bloodline, sick of them healing with no lifesteal and also remove rapidfire cannon or at make it so you cannot buy it with shiv and cut the crit chance to 25% or 20% from 30% not sure why they have 30% where as in other seasons they had lower crit. Revert the changes made to guardian angel where it gives attack damage and make it restore a flat 700 health like it did previously so tanks don't abuse it, this would make their item build look something like / / / instead of their triple crit bullshit with a ton of lifesteal from masteries. For supports make redemption and locket not be able to be bought together, its too much shielding and healing. If these changes seem "too harsh" then they should be adcs are too strong. These changes wouldn't fix every issue with adcs and supports but its a start.
