WHAT STUFF CAN WE EXPECT IN LEAGUE CLASSIC MODE?
In League Classic, several former Riot developers are involved in leading the project. The team has also managed to bring back some legacy client features within the modern client. Some things that couldn't be restored were instead rebuilt to replicate those features.
60 OLD CHAMPIONS (confirmed)
We dont know if we get more, or all of old design champions for now.
