Most heirlooms only work in a limited level range in their default form and must be upgraded to work at higher levels. That costs gold, and you’ll need around 30,000 gold to outfit yourself with a fully upgraded set (counting only those that give you bonus experience). You may need to spend some time on a boosted character to acquire the gold you need to outfit another character with heirlooms, but it’s well worth the effort.
- The auto trash sell feature is also incredible, but I always had issues with it selling gear efficiently. Often I have to open my bags 2-3 times if I have a lot of trash, because it can't clear it all in one go. There's also a very noticeable delay with this feature when opening the bags, almost like the bag UI is freezing for a few seconds, then it clears. I've started using a different add on for auto selling trash and it does it all instant, no hiccups, no nothing. Just one swift move.
Anyway, there are no more shortcuts. There are no more "Tricks". It's just straight questing now since Blizzard nerfed other methods of leveling. You can still do dungeon spam, it just won't be as fast. You can still do BGs, it just won't be as fast. Just about the only alternative way to level that rivals questing is Pet Battles(which makes ZERO sense).
