Guess you have played panth - Taliyah already
I havent tried It yet, but cho - lux must be annoying
As supp, i play mainly meles, Camille Is free as rotate supp, j4 Is so useful against adcs withouth dashes like jinx and subir
I've been playing chogath lately and works pretty good to me, gots so much utility and damage (Cc, silence, R to ensure objectives + do damage) also, with fount of Life you give tons of heal to your team
Sylas supp Is so versatile, the R helsp you so much
Also, keep an eye on swain supp, more After the changes he Is going to get
Neeko Is so useful too and can solo win some games, also you can rotate and fool enemies
Id you want to get something so cheese, Just go hall of Blades azir. You get them allí the time and can do free poke to the enemy. In late game, you have to build as supp, and with your R can change some games
Keep an eye in my history to check runes
