Player characters in BFA, at least according to the lore (not according to the actual idiot who struggles with spiders in Drustvar at lvl 120), are far too powerful now.
It no longer has that… RPG vibe where you are a wanderer thrown to a whole new challenging world, walking a step a time to the goal.
But when you go back to Durotar/Elwynn and start taking quests from town guards hunting coyotes and boars, that RPG feeling which immersed me during the early years of WoW comes back. Of course, I can do those quests with characters that I brought up from other starting zones. But they will simply one-shot the mobs. Anyway, just a random nostalgia kicked in middle of the night.
