Other than the fact that his q is a complete waste of a slot, i disagree. i havent had really any trouble with him lately
4.14 kda, 63% winrate 0/1/17 my last game i believe
Rakan is far and above one of the safest laning supports in game. And that alone is pushing him into something i like. He also has one of the strongest level one's in the game at bot lane. He does need a xayah, and he DOES NEED PLENTY OF EXPERIENCE AT ENGAGING SAFELY, AND PLAYING THE SUPPORT ROLE AS A WHOLE.
His q definitely needs work, i would like a slight range increase, or** FOR IT TO TRAVEL THROUGH MINIONS**, but Rakan is fine. There are champions who are far worse at the role, and far easier to counter. However i would never recommend him to a newer player or support.
