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.
Preface - I haven't played WoW for any length of time since quitting at the end of WotLK. I dabbled in the next few expansions, where it seemed gold was overabundant, not sure if that's what killed the gold farmers/gold bots/sellers, but I didn't seem to see any, or even think I might have a use for them. However, with WoW Classic, I can see a market for them to come back. Did Blizz ever put something in the game to eliminate this after WotLK, or was it the gold abundance that destroyed their market. If not, I see the gold sellers and websites coming back.

However, that’s not the full extent of Blizzard’s announcement. The developer behind World of Warcraft Classic has also announced that it will release a closed beta test for chosen (note this word) players to participate in. The closed beta is meant to test Blizzard’s servers, which I’m guessing will be pretty full once the game actually releases. Blizzard hopes that this beta can prepare them for a smooth launch, since this is pretty big for World of Warcraft players.
If you like playing solo – there’s no better option than the Hunter.  Hunter is considered the most efficient solo-leveling class so you’ll ding level 60 in no time. As a Hunter, you will be able to tame various beasts across the world and use them as your pets. Pets help you tank groups of mobs and enable you to tackle some of the group quests alone. However, their PvE power falls off in the end-game, but their PvP potential is enormous. Skilled Hunters are a pain to deal with since it’s almost impossible to catch a masterful hunter.
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.
