Fortnite’s latest update brings some interesting balance updates to the game as well as a few other changes that have may have gone otherwise unnoticed when you first scan the change list. There are many changes that may seem small at first, but work together in such a way that high-level or even casual play could be changed significantly.

This is a pretty beefy update, and fan reaction was decidedly mixed before the servers came back online so people could actually see the changes in action. The question is how everything will hold up once the players stream in. It’s going to take a little bit of time for everyone to play enough to get a sense for how strategies have changed, and which ones will stay the same. Watching streams for the next few days is going to be an adventure.
