":"  -  Any time a step ends in a ":" instead of a "." means that the next step is part of the current step you are on.  This generally means the next step should be done while working on the current step.  This means every "start working on" or "continue working on" will end in a ":".  But this is used with other occasions as well, so keep this in mind.
Some even more advanced gold makers might also attempt to monopolize the market. It’s fairly easy if you have quite a bit of gold – just buy out every single item on which you want to have a monopoly on and then reintroduce it to the auction house with your new (and higher) price. However, it’s worth mentioning that monopolization tactic is risky business practice. But where’s high risk – there’s high profit.

Where to get materials and reagents you may ask? Buy for cheap off farmers in bulk or track Auction House lots. Get in touch with most big sellers. Communication is important here, send a whisper or write them a letter. It would be good for both of you to establish business relationships. Constant suppliers and buyers is convenient for both parties to save the time and effort.
This did not just simply come randomly, however. Players have been demanding and asking for World of Warcraft Classic for many years now. And Blizzard has likely learned from companies like Jagex that regained a huge portion of their player-base with the launch of Old School RuneScape, which prior to it had a 2006Scape private server. Similarly, World of Warcraft Classic/Vanilla has been around in the form of private servers for many years now and has been very popular. Even top players and streamers have been known to play on these private servers. The only issue is Blizzard were not the ones profiting from these ventures.

You will see a resurgence of power leveling services, item trade services, and gold farming. Classic will have a fresh economy meaning for your average gold farmer time spent in classic is way more efficient. It will probably be worse than it was back in the day. Just look at the blizzard group finder on retail, littered with advertisements for m+ boosting websites. Disgusting. There will be so many gold farmers blizz probably won't be able to keep up. And this is what I truly fear because if the gold farmers start to win activision will step in and introduce wow token. And classic will die.
Kaivax, a WoW forum community manager, revealed that WoW Classic's class design, battleground mechanics and stats on existing items will be set to their 1.12 state, despite the game releasing content that expands beyond that. This removes "progressive itemization," so if the stats on a specific piece of equipment was changed during the original updates, that won't take effect in this version.
All of this is keeping with the spirit of vanilla, which I think is more important than that a specific number be 11 instead of 12. And it would help to "resize the swing" by making the game harder to the more experienced community, and forcing people to re-discover the game rather than simply looking up whatever they want to know on a spreadsheet somewhere.
Tauren’s hitboxes and their melee reach is slightly larger than other races. Being critically struck while using /sit to sit does not cause abilities like Enrage, Blood Craze, and Reckoning to activate. Using the “Automatic Quest Tracking” option does not auto-track newly accepted quests. (It instead will start to track an existing quest once progress towards an objective is started.) Warrior health Regeneration is working at the expected rate. Quests objectives and points of interests are not tracked on the map or minimap. Completed quests are marked on the minimap with a dot. (and not a “?”) Feared players and NPCs run fast. Standing on top of other players while facing away allows spells and attacks to be used. Creature respawn rates are much slower than in Battle for Azeroth. NPCs which offer multiple quests may inconsistently display them as a dot or a “!” on the available quests list. They were inconsistent in 1.12, and we’ve reproduced the exact inconsistency they had back then. Quests that are too low level for do not show up as a “!” in the game world. Available quests do not display a “!” on the minimap. On level up, the message: “Your skill in Protection increased to 15” was added in 1.12.1, and we’re intending to keep that. We appreciate all of your feedback!
Making "new" guides seems kinda out of place. Not only is there still alot of information from back then available, there came alot of information up for minmaxing available for both leveling and raiding, ontop of various bis gear lists that cover patch progression aswell if necessary. Wether people like or dislike pservers does not make the various information found on their forums less valuable.
The system is automated, meaning that once slots are available, beta testers will be chosen, without any beta key to speak of. Kaivax then goes to stress the importance of your account security, stating that, “any third-party e-mail messages, websites, or in-game whispers that offer beta keys or access to the WoW Classic Beta should be considered illegitimate and ignored or reported.”
We’re still looking at how we can best deliver an authentic Classic experience at launch, and in the weeks and months that follow - both in terms of gameplay and community. You won’t see phasing (which is tied to specific quests that don't exist in Classic) or cross-realm zones (which combine multiple realms together) in Classic. However, realm sharding is one of the best tools we have to keep realms stable when hundreds of players are swarming the same initial few zones and killing the same few mobs (like they will be at the launch of Classic). To that end, we do believe that some form of sharding may be helpful, especially in those early days. But we recognize that a cohesive world is critical to WoW Classic and are committed to bringing that to you. Layering in Classic WoW

I think you are referring to the Env Bert strat I have linked. Basically I agree. But you might have noticed that I already had added min power to pet #2, in order to exclude some of the substitutes. Though, I didn’t wan’t to do the same with the Blazehaound (pet #1), because I think the strat is doable also with a suboptimal breed. But maybe you are right and I should just exclude any non-P/P breeds.

Only really to expand on Gráinne's comment as regards the 'collecting' and 'roster development' sections - which are, as said 'distinct' although they are intrinsically linked - I would like to point you in the direction of the in-game Achievements > Battle Pets > Collect tab. There are a series of achievements called Raiding With Leashes, pretty much all of which can be completed via the auction house - if you have the gold/inclination - or by completing old raids.
