No, I do not think the promotion of specifically female eSports is important. But nor do I think promotion of specifically male eSports is important. Also, there is no such thing is specifically male eSports for the most part. Any woman can go and train and become the best in any eSport and just compete in the "regular" leagues/tournaments. Many do and in games like for example Hearthstone they tend to do quite well. There it's again just a matter of how many females vs males are there in total and I would guess that the numbers probably represent the percentages of the genders pretty well.
