Hi riot . why you never fix this launcher . the old client was alot better than this one . most of the time launcher freez in champ select . my system is so strong i have played Assassin's creed syndicate at high graphic so basicy this freez shouldnt happening . its not just me . most of my friends have the same problem . its been 1 year and this issue never got fixed . it si even getting worst.
