We’ve spent a lot of space giving advice for those with less experience in the nuances of World of Warcraft. If you’re a player who generally knows how to get around the game—or did at one point—you’re probably still going to feel a little stuck if it’s been a decent amount of time since you last played. For example, why does your favorite weapon no longer work the way it used to? What’s the latest currency you have to know about? Should you ever waste time hanging out in your Garrison again?
If you love running old content for transmog items, you'll love the new legacy loot system. Whenever a player enters a dungeon or raid where they are 10 or more levels above the content, the dungeon or raid bosses drop an amount of loot equivalent to what would have dropped for a full group when the content was current. That means players could earn loot for five people in dungeons and loot for 20 people after soloing a raid. The legacy loot system also drops other gear types, like cloth dropping for a plate wearer. It's now much easier to get the transmog gear you want, and you can also collect gear for your alts on the same run.
For reference, my previous best time abusing Method-0 in 7.3.5 was 32.4 hours(as show in the old thread). A difference of just over 8 hours; which isn't all that bad, all things considered. And I believe I made several errors along the way, which could be cleaned up in future runs. I believe that that gap could be significantly closed by using a monk's bonus, but I hate playing monk...so...yeah. YMMV
