A Southeast Asian eSports event organiser has limited the number of gay and transgender players per team to one because they have “an unfair advantage”.

In a post on its official site, Garena Sports League announced that the restriction was an experimental move that would only affect the rest of its all-female tournament, The Iron Solari.

“We've given a lot of thought on this subject, and we've similarly consulted and talked with various parties including the female teams who joined the first leg of Iron Solari, and a number of LoL players belonging to the Lesbian, Gay, Transgendered Women community,” the post reads.

"For any events we do, we always want to make sure we are able to have an inclusive environment where no one feels left out, and of course for everybody to enjoy. On this angle, we believed that allowing more to be eligible to join is obviously the answer and as many of our female teams have expressed – Lesbian, Gay, Transgendered Women members are their friends too.

“On the other hand, for any competitions, we seriously look at ensuring there's a fair level playing field for all participants. And there are arguments and concerns from other participants who disputes that Lesbian, Gay, Transgendered Women members may probably have some unfair advantage.”

Any team that breaks the rule will see its members banned from all Garena-organised events for a year.

Garena is an official Riot League of Legends partner.
