Tank Supports in 3v3 have 53 -- 65% win rate. Please also nerf Support Items in 3v3 in 8.6.
Imagine someone in Summoner's Rift had 65% win rate, because Taric currently has it in 3v3. Vel'Koz and Anivia also have 62% win rate, probably because they can run unchecked with no Jungler able to gank them (cause those Junglers are busy farming or can't safely gank without getting stuck in a 3v1).
Just remove Bandit at the very least, please. Make 3v3 diverse again.
