The cloak is nice because you only need one of these instead of the previous cloak versions since the primary stat changes depending on the class it is used on. The on use trinkets for versatility, haste, or critical strike could be very strong if used together by numerous party members with the same trinket. Finally, the threat reducing trinket could be useful for solo levelers in dungeons with newer, non-heirloom geared tanks in order to not pull threat on some larger packs of enemies.
It's hard to step out of the shadow of Legion, which was utterly fantastic in almost every way, to enter an expansion where you get one item per boss in the last expansion because the rules have been changed to force more grinding, where you have to grind reputation in the old expansion that you probably skipped because rep grinds suck JUST to unlock allied races (who aren't fully unique races since they recycle old content such as animations), where questing has SOMEHOW become boring again and where your new abilities are given by items you'll swap out every level, meanwhile being only boring passive effects no one cares about.
I like his recommendations 2 level 1-20 zones to get to 20, then do all the 2nd zones since they are designed for walking (Horde: Northern Barrens, Silverpine Forest, Ghostlands, Azshara, & Hillsbrad Foothills if you need a little more. Alliance: Westfall, Loch Modan, Darkshore, Bloodmyst Isle, and if you need a little more Redridge Mtns, or Duskwood). Don't even bother with the higher level areas, too spread out. Finishing up a Monk now and I had done all these zones before the update, the running between quest and the 50% experience cap is driving me crazy.
The problem with Battle for Azeroth’s endgame is that a culling of abilities, the loss of Legion’s legendaries, and a lack of endgame talents means that hitting the max level doesn’t necessarily make your character more fun to play. Your character is a vehicle to explore new content, and it doesn’t matter how stunning the vista is if the core gameplay loop you’ll execute a few thousand times just isn’t fun.
Any item with a grey name is considered vendor trash or poor quality. White items have some use such as tradeskills, spell reagents or reputation raisers, so you may want to check to see if they're worth more than the vendor price. Keep your eyes out for regular quality weapons, as even the worst of these tend to sell for several silver, or several gold at high level. Always check the tooltip for the vendor price before discarding anything. Also, white (or even grey) shoulder armor under level 20 sells regularly on the auction house, mainly because there is nothing better available at that level.
I'd say level this toon a bit more, maybe up to 30 or so, and see how you like the experience. If you find questing just a means to an end, maybe the guide would be a good buy. Me, I generally like questing and go to an area I'm interested in, even if it's not the most level-appropriate for me or the best way to maximize my time, so those guides aren't of much interest to me for now.
Island expeditions require groups of three players to venture to islands with randomly spawned enemies and piles of AP. The island expedition ends once they collect a certain amount of AP, and they are granted about 300 AP as a reward — unfortunately, players don’t get any of the between 6,000 and 12,000 AP they collect during the expedition. These missions can take anywhere from three to 20 minutes, and never once offer any real challenge or depth.
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.
