Wow is an ancient boomer mmo for grandpa. Back then the virtual world social aspect and roleplaying was more important than cringe esport button mashing and theorycrafting.

Some mmorpgs still had good endgame balance despite of this, because one could offer player to player services. In Anarchy Online, 1 year older than WoW, that would include crafting items, casting buffs, offering fast transport, selling gear for twinking, powerlvling services, clearing dungeons with twinks.
Moreover one had meaningful world pvp where factions could take control of lands, take over cities, and get faction bonuses for being in control (such as exp boosts).

WoW has basically none of this, or rather, only in the most soulless, stripped down retarded way.
