Unlocking the Nightborne is a fairly straightforward process and, if you’ve been playing Legion, you’ve probably done most of the work. For starters, you’ll need to complete the main Nightborne storyline in Legion in order to unlock the “Insurrection” achievement. Completing these quests will go a long way toward earning you the Exalted reputation you’ll need. If you’re not quite there, then you’ll need to grind out Suramar world quests, though it shouldn’t take too long.
When it comes to Classic, Blizzard's goal is to provide an authentic Vanilla experience, but they also needed to come up with technology to handle many players at launch, which is similar to sharding. While the use of this technology will be limited to the first month following launch, many players are questioning this decision and wouldn't like to see layering in the game at all.
I've been playing the Classic beta a little (and I do mean a little, the new Diablo season has me in its grips hard) and I can't see what the big fuss is about. It's Vanilla. That's what it is, that's what it was, that's what was expected and that's what we're getting. Sure there are bugs, upgrades some people didn't want and upgrades other people did want but didn't get, but in the greater scheme of things that's such a small part of the whole, it's barely worth talking about. So why are some people so insanely intent on ruining others' fun?
Other methods have been discussed. For example, mods could be crippled. DBM didn't exist back then, and the other boss that did that I don't remember the name of, didn't do as much back then as DBM does now. If our goal is to recreate the experience as it was, then obviously not having DBM would be a reasonable way to accomplish that. DBM simply existing, makes the game today easier than it was. So disallow it. Again, this is completely consistent with the spirit of vanilla. Remember one-button-decursing? That was nerfed. They crippled the capabilities of the modding API to disallow that because it made the game too easy. So what if they cripple it a little bit more to once again make the game less easy?
World of Warcraft (also known as WoW) players have highly requested the classic version of their favourite game. As with any game, changes and major updates are added over the years. Since August 2006, many changes to the game have not been received well: such as trivialising levelling up. The level cap will drop from 120 to 60, but contrary to how that sounds, it will be a far more grindy journey of fun and progress. The current developers have made levelling up very fast in comparison to the classic days, purely to focus on end-game content and raiding which many people do not enjoy. Prior to these changes, many people enjoyed the games for years whilst not hitting max level, something never seen in the modern edition of World of Warcraft. The levelling process was a journey, having fun with professions and the grind that is no longer found. Of course, there are countless other changes that will be reverted, as you might expect when comparing something from 2006 to 2019.
