The WF/TF system complicates gearing a bit, as you could get an Uncommon quest reward that forges to Epic quality (not a myth - it happened to me on the first night of release). This means that the old ‘Best in Slot' system is, to all intents and purposes, useless, and you should generally opt for whatever item you have that is the highest level - especially as tier gear no longer exists.
I do not recommend going for TBC, although I remember Hellfire peninsula to be decent, everything else is rather slow. Instead go for WotLK, Borean Thundra gets you levelled very fast, and then you can head straight for Icecrown at 67, which is also insanely fast, although admittedly has a few elite quests. You can go to Sholazar Basin alternatively. 2 zones should get you 60-80 no problem.
The prepatch for Battle for Azeroth first hit on July 17th, but the first real pieces of story weren't available until this week (more on that in a minute). The storyline is called the War of the Thorns, and it's intended to hype up the faction-vs.-faction conflict that makes up the core of BfA. Instead, it feels like it's sucking the air out of the room.
World of Warcraft: Battle for Azeroth focuses on the rivalry between the two most important factions of Azeroth, the Alliance and the Horde. The expansion adds two new continents (Zandalar and Kul TIras), divided into islands, where you can find new dungeons and raids, quests and previously unseen enemies, as well as six new playable races. Once again, the maximum experience level of the player characters increases (from 110 to 120). Battle for Azeroth also introduces two new game modes. In the first one, groups of three characters explore chosen maps and fight randomly assigned monsters and threats. In the other mode, groups of twenty characters each try to take over locations in strategic places for their factions.
Was doing it at 52 on my lightforged paladin and it was easily the slowest zone out of the ones I'd done. Granted, I didn't have War Mode on so I didn't have any PVP talents, but it felt like about 40% of my time was spent waiting around for respawns or wandering around looking for mobs to kill to get a quest item that had like a 5% drop rate. Maybe I just got unlucky but I definitely won't be going to that zone again for future heritage armor runs.
Both guides have a different look. Many players choose the Zygor guide because of the way it looks, with it’s modern, clean appearance. Zygor has improved it, so its easier to navigate. Dugi Guides interface blends into the game more, as it looks more like something you would find within World of Warcraft. It has icons down the right hand side for selecting your guides and is really easy to navigate.
And, of course, there are plenty of in-game addons you can use to make your adventures in Azeroth even more efficient. Try checking out Azeroth Auto Pilot, which points you where to go, handles all your NPC discussions and quest turn-ins, and automatically sells your junk gear (among other features). Deadly Boss Mods is still a must-have, so you don’t die in dungeons quite so quickly. Pawn helps you tell whether the gear you’re getting is actually an upgrade or not. World Quests List gives you a much better way to see what’s happening in your zone (and sort for the rewards you’re prioritizing).
That lack of storytelling agency may soon change with Patch 8.1, Tides of Vengeance, which is coming to Battle for Azeroth soon. While there are plenty of fun gameplay changes that should make the expansion better, one of the most interesting additions is that of choice. In an upcoming quest, players will be able to choose whether they want to support Saurfang or Sylvanas — essentially honor or evil — in the struggle for Horde warchief.
