On my server, I can usually craft cards for around $2000/card and decks average for about 25k/deck (average selling price of all 4 decks) . The average profit per deck is around 9k gold, and I can process (on average) 9ish decks per hour. This means that the average gold generation rate of processing linen and herbs is about 80k gold per hour. That also leaves you with a massive pile of red pigments that you can AFK craft to scrolls for extra profit. (Crimson pigments gets generated at 75 pigment/min for "free" when milling for Viridescent, there is an extra 500ish gold per minute of profit when AFK-crafted to scrolls, that's not insignificant)
Valid pieces for Azerite empowerment are available for the chest, shoulder, and head slots of all classes. This equipment has multiple tiers of that can be unlocked, represented by a series of concentric wheels with icons representing individual powers; as individual powers are selected, they rotate into slots at the top of the interface, activating the selected benefit and locking out the others unless the player pays to reset their decision. Outer rings offer multiple choices, some based around the character's class and specification, others around the zone or circumstances in which the gear was acquired. The innermost circle offers no such options, instead being a boost to the level of the item itself, and thus providing a flat all-around benefit.
-Bugs- There aren't too many glaring bugs anymore, but you will certainly encounter some. The pathetic thing is that many of the bugs you'll encounter were reported repeatedly during Alpha/Beta and still weren't fixed. Some bugs were discovered after release and players were able to abuse game mechanics without repercussion unless they were one of the more serious offenders. This gave some players a significant advantage over others because they used exploits and at the start of an expansion, that is the time when it's most impactful.
