Seems Finland's e-sports competition Assembly Summer 2014 decided to split up the competition brackets between male and female to follow what true sports are and legitimize e-sports as an actual sport (because real life physical differences totally go inside the virtual world with the player). Seeing as the finals for Hearthstone are male only though, females can't even sign up to play in the competition.
