As others have said, there are free alternatives... which is important to consider if the price of the Zygor Guides are a concern. If speed and convenience are more important, then they're worth it. Zygor will take you through the quests in the most efficient way possible, and their customer support and the speed with which they update the guides when changes are made to the game is impressive. I know I went from 80-85 a heck of a lot faster (in /played time) than my co-worker who doesn't have the guides. And we had a bet going to see who would make it first. For me, it was worth it. Your mileage may vary...
Assassination Rogues make use of damage-over-time attacks to do the majority of their damage. This makes them incredibly strong single target damage dealers. On top of that, Assassination Rogues have many defensive abilities that allow them to survive a wide range of potential encounters as well as mechanics within raids and dungeons. Their weakest point is the lack of multi-target damage abilities. Their rotation is also very cooldown heavy and is only really effective at dealing with single target encounters.

Nov 7 Game buying guide for confused ppl like me For those of you who were confused as i was, this is about buying the game and what you get so for 15$ subscription - you get all past expansion and 1 month of game time for battle for azeroth (49.99$) - you get the newest expansion for WoW complete collection (59.99) - Newest expansion / 1 month of game time / 110 boost(1x only) I was confused for awhile but now i know that the 49.99$ is the Worst deal ever.

The zone you start in isn't under your control, in as much as it's pre-selected for you based on your race. But for leveling purposes we want to make scaling work for us as much as possible. That means sticking to the lower level zones. Even though scaling will increase the level of the quests and mobs in those zones, the layout and design of them is built for a player with no mount. So you'll blaze through them and gain more exp/hour than higher level zones which assume you DO have a mount.
With Mining, from the moment you take the skill you can make good money selling stacks of the bars or ores in the Auction House. Blacksmiths, Engineers and Jewelcrafters are interested in the bars, while Jewelcrafters and even other miners may want to buy the ores. Make sure to check the relative prices of ore versus bars before smelting. As your skill increases, so does your earning potential. At the maximum level you may smelt Titansteel for a daily fee.
If there would be a transmog server #1, all transmog vendors would transfer there and the market would get destroyed fairly quick. In general, Roleplay-Servers like Argent Dawn or The Aldor are better server for selling transmog. On high pop servers you have a lot of other players selling stuff and as a result, low prices. On low pop servers prices are acceptable, but you have no buyers. So there is not recommendation for a server really. Its up to you.
There are a lot of skills and spells you can train as you progress, each of which costs money. When you can afford to, you should train all the abilities that your class trainer offers. If you're completely broke, it's fine to put off upgrading abilities you rarely use for a level or two so that you can upgrade your most-used abilities. If this happens, you should ask yourself whether you are spending too much money on buying unnecessary equipment upgrades or leveling production trade skills. Be sure to save enough for class abilities and riding training before spending money on other things. This assumes you're earning money at a rate where buying skills makes a difference at all. If you have a hundred gold from two gathering professions by level 20, those skill ranks costing a fraction of a gold won't make any difference to your purse.
Jewelcrafting also offers players the Prospecting ability; players can break down most Mining ores to find gems used in Jewelcrafting. The Enchantrix addon can calculate the prospecting value of an ore, and when combined with the Auctioneer addon, you can compare the prospect value to the ore's value and determine whether it has a fair chance of producing a profit. For example, on most servers Tin Ore has a significantly higher prospect value than the ore itself, and players can make a tidy profit by prospecting tin from the AH. The low skill needed to prospect tin ore makes this a great profession choice for bank alts!
A cool little pet farm that can take minutes or ages depending on the god of luck.  This spot contains some of the most dense troll spawns in the game, and each has the highest chance to drop the parrot pet thats soo sought after.  On every serve rthis per has  amedian value of about 70,000g so picking one up can be a pretty cool feat.  Like the sprite darter hatchling spot its, a random farming spot that requires alot of RNG to pull off, but if you get it to drop you can make out in spades.  The other drops are miniscule when compared to this spot.
