Last thing Blizzard said about it, from what I have seen, is:
For Battle for Azeroth, the Brawler’s guild started with patch 8.1.5 and ended with patch 9.0.1. The new season for Shadowlands has not yet been announced.
Would be nice if they at least could open it so you could do it even if there’s nothing new.
… or an update on what the plans are.
Thought I’d make a post here in case there’s some news about it that I missed.
It’s not a case of hitting a button they still need to tune it. let be frank very few people did it until they vastly over geared it. the same with the mage tower in Legion.
