Marksmen don't need a buff, supports need (another) rework
It's no secret that the marksman role is pretty garbage right now, but IMO half the reason AD's are weak can be attributed to the support meta.
Traditional peel supports have been completely pushed out of the meta by high damage mage supports like Malz, Karma, Brand, and Zyra. When there's no peel, then ADCs are naturally weak and vulnerable.
- Mage supports almost universally crush traditional supports in lane unless there's heavy jungle pressure
- There are no good build paths for tanky aggro supports like Leona/Thresh/Braum that can engage on these mages. Removing CDR from Aegis dealt a huge blow to the playability of these champs.
- It's stupid how mage supports can pump out way more damage than ADCs for the first half of the game, there's just no incentive to gamble on your ADC scaling in when your support can provide all the damage bot lane needs.
- High pressure junglers diminish the value of peel supports when you're way more likely to get a kill than to prevent a kill
- First turret gives too damn much gold, further incentivizing high damage mage supports who can push hard and fast, and punish weak lane opponents who can't wave clear easily.
It's possible ADC's don't need a buff at all, but please consider revisiting supports.
