I suggest we just turn Wild into the league with anti-bot measures instead of creating 2 new leagues. It's just temporary.
Adding another modern and wild leagues will split the player base so much. 2 moderns and 2 wild... the queue would be insanely long for one of those. They might not even get matches at all. Goodluck on higher leagues esp Diamond and Champ.
Also who will manage the anti-bot measures? I don't think the team has capacity to do this.
