Pretty good guide, but I disagree on a few things, such as the Jinx being only average. Her snowball and lane bully is insane.
Very helpful for newer players xD
I think this is a very nice guide for beginners
In my opinion one of the strongest Duos on bot right now would be Twitch and Braum.
Twitch , Vayne and MF currently one of the strongest ADCs.
For the supports I'd say it's Braum , Thresh and Leona.
I like
Sona+Ashe
Sivir+Karma
