Nexus Blitz will not be returning at this time, despite Riot having previously stated that they will close the year with it. Unfortunately, unrelated development on a separate aspect of the game disrupted some of the NB UI experience.
Since they made the original promise in 2021 to bring back Nexus Blitz, the League team lost some key people that would’ve been involved in this. Rehiring for roles and onboarding new members takes time that impacts respective projects.
This means the amount of work to fix Nexus Blitz will take longer than Riot had hoped, and isn’t something they were able to complete in time for the end of 2022. So the dev had to make the call to not run it.
The dev team apologizes for not being able to fulfill players’ requests for the return of Nexus Blitz at this time; they realize that this is not the news players were hoping for.
The Dev team prioritized the most current ARAM changes when working on live modes, but they also have plans for other, both new and ancient, regions. Early in the next year, Riot will offer a more thorough update on both what led to the tragedy and the future of League’s modes.
