The raid is made up of eight bosses that each have interesting and unique mechanics. Some bosses might put extra pressure on the DPS players to kill an add before it can heal the boss, while others might require players to move around the environment in a specific pattern or order, all the while still doing as much damage to the boss as possible or keeping the group alive through healing. While past raids often repeated mechanics or had one or two boring fights that didn’t ask much of the players, each encounter in Uldir feels unique and challenging. It’s been a long time since we had a raid where each fight was as much fun to do over and over again as the fights in Uldir.
For your tank... I'm assuming you meant which race should you be, not which class, since you seem to want to be a warrior! Well, if you were Horde side I'd recommend Tauren for the health buff. But honestly, I *never* pick a race based on the racial features - only based on the flavor. If you are going Alliance side, I am quite partial to dwarf warriors myself but pick whatever seems most fun to you!
Through out the game, the quest log will be capped to 20 many times.  The guide makes use of maximizing the total amount of quests you can accept at once.  Because of this it is important to follow the guide exactly and only accept quests if the guide tells you to so you won't run into issues not being able to accept a quest.  If you do accept a quest that is not listed in the guide, write it down because you may need to abandon it in order to keep following the guide if your quest log is full.

Footholds into enemy territories can be done as you grow in levels and should be completed before reaching Level 120. Take the time after completing your first zone to do your first foothold, or you can choose to complete one as soon as you gather your 100 War Resources which will prompt you to return to your mission table area where the first foothold quest can be obtained. Similar to how your initial zone selection was largely irrelevant, this selection is, as well. Simply pick one and complete it to earn your Mission Table second champion. Send your champions out on missions, recruit troops, and then head back out to quest in your second zone selection.
I highly recommend actually staying in the 20-60 range zones until you ding 62. The reason for this is that despite getting a slight penalty in experience for being over-level, the advantage of having flight will more than offset this. That, and WOTLK and TBC zones are the slowest part of the leveling process. Minimizing your time there as much as possible is worthwhile.

Yes. I believe so. It plays nice with most Addons; even many that are out-dated. The only Addon with known issues is the mini-map in Bandit's UI (the rest of Addon works well with this Addon). The issues with Bandit's mini-map are fixable by disabling its mini-map (how to do that https://i.imgur.com/2zl3IEV.jpg) and using Fyrakin's Minimap. I found no issues with Fyrakin's Minimap. I have not testing other mini-map Addons but I assume the results should be like Fyrakin's.
Isle of Quel'Danas: Special mention. At lvl 70 you can start doing the dailies here. Despite not being able to fly, the quest density is VERY high. I recommend hitting this every reset if you spend more than 24 hours REAL time(not /played)in the 70-80 level range. In fact, if you're doing a monk and only logging in once each day anyway, IQD WILL be your best exp/h for this level range.
As for the classes themselves, they almost all play like slower and slightly less interesting versions of their Legion counterparts. This is thanks in large part to the loss of one ability from each class that came along with Legion’s own AP dumping system: the artifact weapon, which added a unique ability to every spec in the game. The loss of these abilities left most classes feeling frustrating and incomplete, and though Azerite gear was supposed to be the replacement, it missed the mark completely. There will always be one Azerite trait that reigns supreme for each spec, meaning that the frustration of that particular loop will be unavoidable as long as the system is in the game. 

These stat priorities help to get a rough idea of what gear to go for, but the most important thing to get as soon as possible is your stat weights. Stat weights help you zero in on which stat is the most effective at increasing your healing. However, healers have no grand simulator, as there are a lot more variables that can affect your overall performance than there are for DPS specs. In light of that, healers use fight analysis tools like WoWAnalyzer and the Teachings of the Red Crane spreadsheet that takes logs from WarcraftLogs and gives you accurate weights that would improve your output.
That’s because armor of higher level has higher Azerite power requirements than lower level armor. That means a shiny new piece of Epic gear will have better stats but, unless you’ve been diligent about your Azerite power grind, won’t have as many traits unlocked. You lose options as you earn better gear. Eventually, you’ll grind out enough Azerite to earn those traits back, but you’re left with limited customization until then.
