I am using champs basing on my own experience and some recent statistics.
If you ask me why did I put every champion in it's tier - I can answer you. I'm ready to talk at any moment when I'm online.
Vote if you like my tier list, I will be very grateful :-^)
Tier list is generally updated every week and has some minor updates every 2-3 days.
RIP - lower than tier 2.
If you have questions you can ask me on my Twitch channel when I'm streaming https://www.twitch.tv/mrjerichoo
I can speak both Russian and English.
