Fix the Premade Groups/Custom to be like it is in retail.
It’s not even cross server at the moment, so if you’re on a server that’s not Benediction for Alliance, then it’s slim pickings to find arena partners.
It should be cross server, it not being cross server at this point is backsliding from user interface upgrades that have been available for years.
Also, it’s cluttered, instead of having a custom pvp option where you can select 2v2/3v3/5v5 or BGs/RBGs, it’s just a cluster of random Custom premade groups that you have to filter through to find anything related to what you’re looking for.
Please consider doing this!
