Why don’t you go for a Guiness World Record? (The answer is that I applied for the World Record as Richest Player in World of Warcraft in November 2015 but they “do not invite proactive applications for records such as the one you are proposing” and suggested I go for “world’s longest Warcraft livestream” instead. Zzzzz no skill needed, no thank you!)
But the system offers a painful and mindless grind. At worst, it feels like a cheap and artificial wall blocking you from playing your character to its full potential. Levels of your heart come fast at first, but the costs become prohibitive when you get up into level 20 or so. This wouldn’t be an issue if the most powerful Azerite gear didn’t require reaching level 22 to unlock even 75 percent of their full damage, leaving players left out of features from gear they’ve already collected. This means more grinding.
You’re after all the items to make the Super Cooling Module from Shadowmoon Valley, Nagrand or Talador, and the Cyclical Power Module from Frostfire Ridge, Gorgrond or Spires of Arak. Some are worth only a few hundred but I’ve sold a few for over 20k. They drop from any mob in the zone. I haven’t found an optimal spot, but all these zones have plenty of areas with densly packed mobs.
2. Once you have an interested buyer, stay firm in your price. This does not mean to never make them feel like they are getting a bargain. You can subtract 5% off the price and not be hurt as long as you still make a profit! Remember this, as that 5% may not be a big deal to you, but the buyer will feel special and might buy the item for the slightly reduced price. I can not emphasize enough that this is not the same as undercutting! Do not drop every good every time or you develop a reputation as a soft seller and people take more liberties in their dealings with you. If you give someone a constant 5% discount, then they begin to want 10% and then 15% until you no longer make a profit. Discounts are used when you feel that the seller may be pulling away and you really want to just profit and move on!
