This is something that people really need to start to understand, not just for Classic or WoW but software developement in general. Fixing a bug isn't just flipping a switch or changing a single digit. You have a machine with literally hundreds of thousands of parts, designed by dozens of different people at different times over the course of 20 and more years. You change a single thing and it might break 50 other things in very subtle ways that might not even emerge until months later (i.e. the very high M+ keys some players got at the start of BfA).

Nov 15 Classic hit me like a truck I had no interest in it what so ever. After watching the blizzcon demo - I can’t stop thinking about it. The combat it’s so visceral. The world is so much bigger and so much more dangerous. Each fight reminded me of dark souls. I’ve been watching only classic and vanilla vids since blizzcon, it’s actually ruined retail for me. I was actually enjoying raiding in BFA but now I don’t want anything but to play classic and immerse myself in it. What is this sorcery? I heard vanilla wow was addictive, but really? I feel like I’m in withdrawal and I haven’t even played it yet. I think I’m in trouble once it releases. I don’t want to log into retail anymore :(Gripp204 Nov 15
There’s the reason why some players used to call the game World of Roguecraft. Rogue was one of the most popular classes in classic WoW and there’s a good reason for it. During vanilla, Rogues topped DPS meters in raids and dungeons, but their main strength was world PvP. Rogues could stealth through enemies avoiding unwanted engagements with the opposing faction. Additionally, a huge variety of crowd control abilities and high burst damage made them the worst nightmare for the cloth-wearing classes. However, Rogues were in a bit of disadvantage regarding end-game gearing since most of their gear pieces were useful to other in-game classes as well.
Another way to make gold. This option works well at level 60 when you have some good gear already. Obviously, you should have some gold ready to buy reagents. Be ready for expenses up to 225 skill points in any profession: items below that are not worth much. You will get first income after 225 skill points in Leatherworking, Blacksmithing, Alchemy or Tailoring. Unfortunately, Engineering and Enchanting will still require some investments.  The only way to make gold with enchanting is disenchanting skill (we talked about it).
The quickest way to level up is to travel through the game's zones, completing all the quests you encounter along the way. Completing quests grants you Experience points, which will slowly fill in your experience bar with blue or purple. When the bar fills, you reach the next level. Alternatively, you could choose to run Dungeons or Battlegrounds, which are not covered in this beginner's guide.
Sharding eliminates server load and realm stability. Cross-realm sharding is here so that players are evenly distributed across realms and helps combat underpopulation. Sharding at launch is vital to ensure a stable launch of an expansion. Starting zones would be filled with millions of people and that would turn even accepting a quest into a nightmare. Disadvantages of Sharding

You can opt in for the beta at the official site. When the beta launches on May 15, players who’ve gotten in will be able to play all the way from from level one to 30. WoW game director Ion Hazzikostas tells us that the beta will be “uncharacteristically small compared to our expansions,” in part to ensure that the focus is on the proper launch this August.
A lot has happened in World of Warcraft in the fifteen years since it originally launched, and over that time we’ve come to expect certain things, not just in WoW, but in games in general. As players explore Azeroth as it existed back in 2006 during the WoW Classic beta, they’re reporting bugs – but in many cases, these ‘bugs’ are really just features that are working as intended.
