A day we expected to come but now Riot Games have formally announced that their Vanguard kernel-level anti-cheat is coming to League of Legends, and so it will make it unplayable on Linux.
Hopefully we can still get some traction going against Vanguard, Windows users haven't been the greatest fans of the system on Valorant, maybe with enough voices riot will think twice about it?
We still have a few possible outs though, Vanguard is not gonna be enabled on the macOS version, so either we can convince riot that Linux is as big of a platform as macOS or we can hope for Darling to get to the point where we can play games with it.
