Since WoW Classic server has been announced at Blizzcon 2017, there is not much info about the server revealed. It is known that the upcoming expansion Battle for Azeroth pre-order has been available at blizzard shop, and the system requirements of Mac and Windows has been unveiled Recently, Forbes has an interview with J. Allen Brack and Jeremy Feasel about the project and some of the vision that developers have.
My main plan will be to focus on raw gold in the beginning. Then I will spend my gold on leveling tailoring and enchanting so I can shuffle enchanting materials which is likely to be very profitable. I already have some shuffle ideas, and I will look for more. Then I’ll work on obtaining the rare enchanting and tailoring recipes to craft those for gold. 
I am currently working full time on my Vanilla WoW leveling guides.  Soon there will be a 1-60 speed leveling guide for Alliance, along with in-game guide versions available for my members area.  As of right now, there is no members area, but if you would like to show support for my efforts into this project, you can simply donate to me via Patreon if you like (you will get some cool rewards in return).  Or you can donate directly with PayPal if you like.  All donations are highly appreciated and they will only motivate me more to continue making the best vanilla WoW leveling guides on the web.
The item they're dropping is the Fused Wiring used in a variety of engineering recipes such as: Field repair bot, Gnomish cloacking device, Goblin jumper cables, mechanical dragonkin and so on. The drop chance is estimated to be around 6% and due to the fact that there only 3 spawn points and this is the only somehow efficent place to get it... the price of it on the auction house is anywhere between 5 and 10 golds, sometimes even more.. you know.. supply and demand.....
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.
Swim Speed Potions (used especially at lvl 37 for Faldir's Cove in Arathi Highlands and lvl 57 in WPL).  Try to get multiple stacks of these.  I also recommend keeping a stack of these always in your bags.  You will frequently pass rivers and lakes and can use these potions to pass them faster through out the guide.  Please note that these potions do not stack with Druid's Aquatic Form and Glyph of Aquatic Form.
Nov 15 Classic Box Cost Disappointed in the decision to bundle the subs and (at least for now) not have a separate Classic sub option. That said, can we at least get a separate box cost for access to classic? It would: - help alleviate temporary bloat and subsequent dead realms - servers would be more stable population-wise over time - remove the bulk of the need for sharding - give a solid idea of how many servers will be needed - allow blizzard to set up a separate classic forum for those with a monetary commitment - with a separate forum group, feedback would be limited to those with a vested interest The subs would still be bundled, but there would be a box cost, akin to what one would have to pay for BFA access. A very good to-the-point post from later on in this thread:... Another good post about how the current setup would necessitate sharding:... A decent (albeit short-term) alternative:...Brokenwind314 Nov 15
Most profitable professions are considered to be Herbalism and Enchanting in pair. You can have Enchanting only for Disenchanting skill, it will bring decent gold. Consider the fact of disenchanting all soulbound armor, not just selling them to a vendor, but I do not recommend to disenchant any kind of weapons, it is more profitable to sell it to a merchant if it is a soulbound item, or sell it on auction house if it is BoE (bind on equip).
Nov 15 Loot sharing. Fools How stupid is the community about loot sharing? You know there is master loot right? Stop being dumb guys like holy crap. You also know that if you're the guy setting up a group or joining a group you have a option not to run or you can pick player's of different armor types... If you're a cloth wearer you just don't run or set up a group with other cloth wearers. Like this is something so simple and the community can't graps anything. I feel bad for blizzard sometimes with having to deal with brain power of this community. The community: "Oh, I didn't think about that. Derp, I'm an idiot."Plewtoe23 Nov 15
Nov 15 Which class are you planning on rolling? I'm still trying to decide between: Orc shaman: enhancement until 60 then resto for pvp Undead priest: shadow unless I decide to raid a bit Leaning towards these healers since I don't mind the role and 5 mans will be insanely easy to pickup. I've also been tossing around the idea of rogue/mage since that is what I played back on during vanilla/BC (had a blast ganking).Xano24 Nov 15
