This list is focused on the champions that have the most success in solo queue. In simple terms this list is a ranking of who I suggest you play right now if all you care about is winning games. Above is an accompanying video on the top two champions in each role that elaborates on exactly why they are the best choices right now.
Chances are you may disagree with where I have placed your favourite champions but remember that everyone on this list is at least strong in the current meta and there are plenty of viable champions who are not listed here.
I'm not going to include commentaries or guides next to each champion but if you're interested then you can find videos for most on my youtube channel along with a bunch of other content! https://www.youtube.com/user/ThePhylol
