Honestly, Support itemisation is like half the reason ADC feel so oppressive to play against
Supports got a huge buff to their itemisation and impact with Riot introducing items that add a bunch of additional effects to their kit. Prior a Support's worth came from their base kit but nowadays they get a bunch of fat utility items to blow their impact out of proportion.
Makes their ADC almost untouchable and it has actually become a staple TOP LANE item
Completely negates most engages and AoE combos
Is actually in a reasonable spot right now but was completely busted on release
Is just disgusting, making ADC's actual drain tanks with huge AS and 20-35 HP on hit just tacked on for good measure
I just think Supports are just as responsible to ADC's being overbearing than ADC's alone. Hell, death's dance is only really built on Draven and PD isn't that much of a problem anyways.
Fact is that most Classes who rely on destroying the ADC are getting cock blocked by even bigger amounts of peel that Supports got in addition to their already good kits.
EDIT: Knew this would happen. Supports AMPLIFY the issue of ADC's being overbearing due to their entire purpose being keeping said ADC alive. Their itemisation gives them too much peel/shielding/healing power. Doesn't mean ADC's are innocent, far from it, their damage coupled with lifesteal is just too much at this point as it has been buffed countless times. Meanwhile Dcap still feels awful to build.
Edit 2: Aaaaand we got people say this is circle jerking about Supports being "too strong" Seems we can't just have a reasonable discussion about support without people getting butthurt about it.
with
she has gotten almost nothing but nerfs since her release and shes one of the oldest supports.
lifesteal
is better with DPS mages than burst mages, but that doesn't mean DPS mages are more powerful.

, lethality in general
