You say decades but esports really only has started giving opportunities to women after 2010s
and even then most of what they got was pretty scarce
They just need more time, you cant expect gc to be around for 3 years and already be able to beat teams full male teams.
Riot is really the only company pushing for equality in esports, so yes its gonna take time but it will eventually be a reality and you cant deny that.
and also mel was denied cause one of the players didnt want to play with a girl, that was confirmed and you can check your self
