Things you should know before choosing to become a Miner:
If your primary profession is either Blacksmithing or Engineering, Mining
is practically a prerequisite. Both professions require materials that can
only be acquired through Mining. You could choose to not take up Mining as

Mining is a great way to make money compared to some other professions. Unless
you intend to take up Leatherworking, Mining is a good profession to consider.
The only way to make large amounts of money through mining is by selling Arcane
Crystals and Blood of the Mountain in the Auction House. Both items are extremely
rare, however, and you shouldn't become a miner solely to farm them.
There is quite a few handy tips divided into sections for easy reading. Enjoy!
