It's not certain just how Nanzer will shape Fortnite esports, although it's likely to be significant when he was the one who got Overwatch League off the ground. He pitched the idea to Overwatch lead Jeff Kaplan back in 2015, well before the game even arrived, and helped enlist support from both major financial supporters and teams. The league is now one of the largest esports entities, complete with major sponsorships and, as of 2020, home games. It wouldn't be shocking if Nanzer built up Fortnite in a similar fashion.
Overwatch League might not change much with Nanzer's departure ̵
That's why I'm confident the league is in great hands. I can't wait to see the team taking over the Overwatch League in 2020 – and beyond. And I'll be cheering right there alongside you, every step of the way. 4/4
