Stormheim is the zone you want to start it. For some reason Legion treasures are not worth any experience like they are in WoD...except in Stormheim. I haven't been able to find out any reason for this, and it's possible it may get fixed/nerfed at a later date. But for the time being you REALLY want to jump from treasure to treasure to augment your quest experience.
This kind of storytelling comes with problems, ones that players have been facing since the early days of the silent video game protagonist. Players in World of Warcraft have so much agency and choice when it comes to their own characters and how they build them. But despite their importance to the world itself, they can do nothing to change its story.
There are addons for ElvUI on Curse, but unlike the other addons on this list, ElvUI itself can has to be downloaded separately. Despite this, it is probably the most useful in terms of UI customization. ElvUI is a complete UI overhaul that allows you to fix many of the basic customization issues that the original WoW UI has. The big drawback to ElvUI is that it is a bit of a time investment when you first download it. It takes a while to get used to, and you’ll have to take the time out to fully customize your UI. This can feel vastly different from other addons that are mostly set immediately once you’ve installed them. If you’re willing to put in that time though, this can be a really effective tool in organizing your menus, and having a better visual experience playing WoW. With this addon, you won’t need some of the other ones, such as Bagnon, which ElvUI already has built in.
The quality of captured wild pets is random. As of patch 5.1, upon entering a battle the Pet Battle UI shows the quality of a wild pet (idicated by a color-coded border around its icon). If you're farming a specific quality, if you forfeit the match your team will incur a small damage penalty (roughly 10%). There is no accurate way to determine a pet's quality prior to the start of a battle.
