I don’t play WoW for “other players’ expressions”. I play WoW because I want to be immersed in the rich fantasy setting that Metzen and other folks built, presenting us a wide variety of cool options, all of which were firmly grounded in the setting they’d built.
I enjoy how Night Elves are this super unique interpretation of elves, not really firmly committed to being “Dark Elves”. How being a Druid implies a very particular and specific connection to nature, which is different even to Shamans. Things like that.
If race and class are completely without any sort of meaning, then the ONLY things that will matter are “tier-lists”. Or, at best, “how they look”.
