Saw this mentioned on GD and had to agree - they should look into bringing back blacklisting for some maps in unrated BGs. I know I personally leave Seething Shore literally every time it comes up because I can’t stand the map, same with Ashran too in epics.
I know it might be less plausible in epics since there are way fewer maps, but at the very least regular random BGs should have blacklisting added back. Blizzard did remove it when they separated epics out from smaller BGs, but the addition of maps like Seething Shore and the Deepwind Gorge remake have really necessitated it returning IMO. Just a thought.
