Since the beginning of Season 10, "Tyler1" decided that the ADC role wasn't suiting him anymore and he embraced the Jungle role. What started as the half of a joke became a real challenge over the weeks, as the 25-year old streamer actually tried to prove that Jungling is by far the "easiest role" in League of Legends.

After weeks of tryharding, 947 wins, 864 losses, and a 52% winrate, Tyler1 hit Challenger yesterday.
Over these almost 2000 games, Tyler1 mainly played Olaf, with whom he achieved a 47% win rate over more than 400 games.
It remains to be seen if he will continue his journey into the Jungle or if he'll switch back to his previous role...
