Everyone laughed when he was spamming Naut supp
For the record, prior to his rework almost 20% of Nautilus games played were as a support with a win rate of roughly ~49% which was just about the same as is jungle win rate. LemonNation didn't invent shit, he just capitalized hard on the buffs, same as any other Nautilus player who recognized how strong the E changes were, be it jungle, support, or top. Naut support has always made sense.
Olaf support and Trundle support are meta dependent. Just like when they're played top, once ranged AP supports came into play again they're going to get fucked.
