I don’t play Epic BGs, and I don’t do arenas. I only do RSS for Conquest gear, and perhaps an elite set. I haven’t taken part in Yolo RBGs since Willow left.
All I do is Random BGs; they’re my expertise. I’ve hit maximum level with every class except for Hunter, although I have played it at the maximum level during Dragonflight (I won’t delve into details). I’ve topped the charts on every class. Put me with, as you mentioned, one or two peeps who are dedicated and knowledgeable about their classes, and I can consistently top charts in any BG we queue for.
It’s not a matter of class balance; it’s an issue of coordination
