This is why Epic has announced a new approach towards updates where in the future, they will be hitting the pause button on Fortnite Battle Royale updates ahead of competitions. This is to give professional players time to adapt and adjust their strategies, versus introducing patches right before where a strategy may no longer be viable.
According to Epic, “We value the ability of players to adapt to the game changing over time. We also believe these changes keep Fortnite fresh for everyone including players, competitors and spectators. However, we want to provide reasonable time for you to adjust strategies following large gameplay impacting changes, for example prior to official Fortnite competitions. This time window could range from a few days to a week of a release.”
These changes are expected to take place at the upcoming Australian Open, where the updates will be put on hold. However once the competition is over, regular weekly Fortnite updates are expected to continue as per normal.
