As a ADC, tanks are the best support
I only play ADC / support and I can say that tanks are the best. I feel 1000% confidence when I’m with a tank. Even better if the tank can stun, as a main Miss Fortune the ulti hits so good when the support does its job.
Obviously, some people might think they are boring to use but I can say that I’m my best when I’m with a tank.
For example, Leona can stun aoe when they are doing dragons o baron and I can do the ulti from behind. With that combo you can easily kill and steal objectives.
EDIT: I don’t like Yummy, Sena and Seraphine. I mean they are alright but as a support meh. I don’t think healing is important in this game, you can just back up to the base and heal. Supp can also use the healing spell.
