This isn't how things work when you watch Fortnite items generally, nevertheless. Fortnite is very fun to watch streams when it's high tier players moving up against the overall population. There, the main objective is to put on a show for audiences, which along with the overall skill level of players like Ninja, DrLupo, Myth, Courage, etc, results in some exceptionally entertaining matches that combine humor, action and high-performance play.
Similarly, there have been fortnite guns"events" which are still entertaining, even if it is not just watching pros stream against randoms. Ninja threw a very fun event in Vegas where he played against other streamers and some fans, but it was based around his appeal specifically. We watched his flow, we watched other players try to collect a bounty on his mind.
The championship pairs YouTubers and streamers on a team, and makes it a 2v2 points match where each half of the squad must rack up as many kills as possible in a game, literally hunting the general player population for sport.
This may not always end in wins, but it does encourage survival as though you're dead, you can not continue getting kills, but the key idea is that it gets the matches entirely about actions, since kill totals are the most important objective.
