I'm thinking about buying a second account to power level alts for the heritage armors. Does anyone know if this is still worth it? I was reading that it was nerfed but can't seem to find any guides from 7.3.5 and beyond that show anything one way or the other if taking a 110 to mow stuff down works in dungeons still. Is it just quicker now to quest/dungeon?
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.
I've used WoW-Pro for years and in WoD, Legion and now BfA it's been awesome for just going on auto-pilot and working your way through a zone. It has 3 levels of depth you can set, so you can set it to just do 1) the main story, main points of interest and rare mobs and treasure that aren't far off the beaten path; 2) every quest with a more thorough dive into the side stuff; 3) absolutely everything.
