I just asked someone to watch your video with me. Aside from the obnoxious toast dings from Bnet and your own effects volume for pally spells, we can definitely hear the druid swipe/thrash sounds and some other things. Yes, they are lower than your effects, but they are still there. However, the staff addressed why this volume disparity is happening in the last thread and there have been no changes since then.
They also mentioned where to post feedback if you’re unhappy with it, but you said you were quitting instead.
