I never understood how people were unable to level alts without an exp boost. It does help a lot, so please don’t take this out of context. But anyone who quests shouldn’t have any problems at all. Plus the lore makes the game that much better.
My personal favorite questlines are the goblins out in thousand needles and anything Freya related. Freya is such a bad***.
Edit: Heirlooms are sweet. The only nitpick I have is that there is not a complete set in wotlk. Also if loremasters could have a permanent exp boost with their tabard, I think it would be a massive QoL improvement.
Wrath Classic was released without RDF to begin with. (It was added later when DF and awful Titan 5man content implementation strangled the population.)
Classic didn’t release with any BGs in 2019…
Balance? Sure. Final Patch
Social Mechanics? Much more wiggle room.
