5v5 solo queue tier list updated 12/23/2018
is super strong and can be used to carry without very much trouble
is not a strong as an S grade champion but you shouldn't find any problems in a 1v1. gun mage is in this tier
is not a super strong choice for solo queue but is still fairly strong and usable
borderline useless for a solo game
almost impossible to win a game with these champions in a solo queue unless you are facing only bots
all of these are my opinions. please leave a comment if this helped or if you have any questions. i have a link to a google sheets doc version that includes a team fight tier list as well as notes on each champion for both solo and team fight queues set as my profile's web page in case you want to check that out as well.
also, on a side note. if you are new to 5v5 then you will probable need to play with a team for a while to practice these champions. make sure to jungle with the assassins between waves so that you can out level your opponents and maintain level advantage throughout the game.
