Sometimes that requires players to earn gear to give them greater powers that they haven’t yet unlocked. That sense of progression is at the center of what makes World of Warcraft great and so successful over the last 14 years. There should always be a balance between gaining gear and strength through lower-level content and taking on the hardest challenges the game has to offer. With Battle for Azeroth, Blizzard has missed the mark. Getting to elite status just requires grinding content that isn’t fun, instead of players demonstrating their skills.
Mechagon and Nazjatar will both be endgame experiences that draw on the best elements of previous endgame grinds: the Timeless Isle, Argus, Tanaan Jungle, and the Broken Shore. Azshara’s domain of Nazjatar will be a little more typical, while Mechagon will be “what you might expect from a gnomish paradise,” says Hazzikostas. He describes it as more sandbox-y, unpredictable, and akin to a playground. Both zones will have flying enabled.

I made some route changes to the Horde levels 43-44 sections.  I have swapped 44 Dustwallow Marsh with 44 Desolace (the entire sections). This allowed me to do Deadmire (at lvl 43 instead of 38) and then go stop at TB to turn in Deadmire + The Black Shield at the same time, then fly quickly to do the Desolace stuff.  Doing 44 Desolace is now mandatory because I think its faster with the new routes. This will also make the level 53 grind much shorter.  I think these were great changes.
Okay, this farm is by far my favorite old world farm.  Generally because discovering this spot is like finding a hidden gem that the developers do not want you knowing about.  The thing is, everyone talks about farming zul farrack by pulling the entire instance... Nope, the real gold is made by flying over zul farrack...  If you fly over zul farrack until you reach the large steps that begins the usual third boss scenario, you will find that there are literally 50 trolls just hanging on the steps and another 25 just sitting at the foot of the steps.  It's an amazing scene, as all these trolls have ACTIVE level 40-45 loot tables.  Each and every one of them can drop cloth and mogs from the mid level era of items.  Whats more is they don't take too long to respawn.  ALSO they are not affected by the 7.3 transmog nerf because they ARE NOT in an instanced zone.  Making this spot the BEST transmog spot in the game IMO.  Check it out in the video, it's really awesome.

Starting off at some mid level? Come into the guide from any level, scroll through, find and click the level you want to start with, and the guide will take it from there. Zygor suggests starting the guide a level or two before your level. This is to allow you to work you way into the local quest chains. Just skip the chains for quests you didn’t pick up along the way, or the quests that you already did.
No he's just not paying attention. The wanted quests are built into both the leveling guides and the "Zandalar Forever" achievement guide. They aren't in the rep guide because they are not repeatable and by the time you hit max level they should be done. You'll also notice the rep guide doesn't contain every single possible completable quest that rewards rep. It is designed to focus on repeatable objectives, world quests, large quest lines, and missions.
