Support problems

kits of true supports are extremely undertuned, which leads to more non-supports (Zyra, Brand, VK, Annie, veigar, Trundle, Nauti, Blitz) in support role .

true supports cannot be meaningfully buffed because of the outrage (OMFG JANNA 54% W/L GETS BUFF QQ RITO BUFF AATROX)

support items are what makes and breaks true supports. Actives are way too strong while passive stats are too weak. This leads to same boring gameplay that plagues all true supports

healing and shielding is too reliable, promotes passive gameplay and has zero counterplaycounterplay. HOTS has some good support designs worth looking at, especially auriel and kharazim

all true supports focus on protecting/saving allies. Not one of them focuses on making allies more powerful or enemies weaker, zone control, wave control, objectives or anything besides protecting or CC.

ADCs are used to supports sitting on them and erasing their mistakes, so they despise anything different, which leads to skewed winrates.
