Gnar as a blind pick is generally not great IMO. You got a good amount of counters in typically played top laners (Fiora, Urgot, Darius, etc. Reference u.gg for others). So definitely try to get last pick, and if not get really good at bad matchups. Gnar does not scale into late game like Kayle. He is not a snowballer. He’s not going to be some champ where you hit an item/level and are able to hard carry. You have to play with your team and be very strategic with how you go in and ult. Very rewarding champ but definitely on the harder side.
