Although the Company follows the procedures set forth above to protect the Personal data submitted to the Company, no method of transmission over the Internet, or method of electronic storage, is 100% secure. Thus, while the Company strives to use commercially acceptable means to protect your Personal data, the Company cannot guarantee its absolute security.
Potions serve more utilitarian purposes, and it's up to you to decide whether to make use of them. The most common is the Swiftness Potion, which can provide you a handy boost in speed while going after annoying quest objectives indoors. These are generally MASSIVELY overpriced, because people know how useful they are. I opted not to spend the gold since Warriors are already fairly mobile, but slower classes may benefit greatly from these.
Most BfA Alchemy recipes have 3 ranks. Rank 2 reduce the materials required to create a recipe, and Rank 3 have a chance to create multiple potions/flask etc. Higher rank recipes also give skill points much longer, so it will be a lot cheaper to level Alchemy if you first get Revered with the new BfA factions, because you can use cheaper recipes for longer.
Skinning is a good money maker as throughout your travels you will fight many beasts. It also won't take much time, only 1-5 seconds after every beast. Miners and herbalists have to travel all the way to the nodes. Skinning also provides the passive bonus Master of Anatomy, increasing critical strike (which is especially helpful for agility-based characters who take it with Leatherworking).
Also note that power leveling is sometimes used to refer to paying someone else to level your character to cap as fast as possible (i.e. they power level for you); a distinction used by Blizzard is to refer to the paid leveling as "power leveling service." This behavior is against Blizzard's Terms of Service. Power leveling yourself, which this article covers, is perfectly acceptable.
