Awesome trick really. In this farm we'll be taking advantage of game mechanics to exploit a way into getting more defias loot drops. The defias leggings and gloves have respective selling prices of 3,000g and 14,000g and only drop from 1 mob in the instance a staggering 1% of the time. But do not fret, we can get the upper hand on this. Much like past drop-combat farms, if you kill just one of the two defias overseer's in the instance, THEN drop combat, the one you killed will instantly respawn. The trick here is to bring a character that can consistently drop combat and score many more kills than the average farmer. To date, a hunter is best – with night elf being slightly better because of shadowmeld. You can also bring potions of invisibility to boost the effect. Anyway, while the average farmer only gets 1 shot to get these super rare xmogs, with this method you can get up to 40 chances in an hour. Seems fair right?
This is not to say that you should never buy gear. Having equipment that is reasonably current while leveling allows you to kill enemies faster, and die less often in the process. Faster leveling = sooner to higher levels (where the real money is to be made). Likewise, death = loss of time. And, as we all know, "Time is money, friend!" So, players should not hesitate to make well-considered equipment acquisitions during their leveling up, but only if they represent a substantial improvement over their existing equipment and if the price is right. Try to find good deals. It should go without saying that you should never purchase any equipment from vendors; always use the Auction House. Look several levels above and below your own for bargains. Don't buy items that you won't hold onto for at least 4-5 levels. And don't always use the buyout option at the AH. Some of the best deals come from bidding and being patient - it'll be two days at the most. Of course, if you play too hard you may have surpassed that weapon by the time you win it. In which case, you may want to auction it again. If you know there's an item that would be great for you, say, five levels from now, keep your eye out for it and bid on it, several times if need be. When you get it, stuff it away for later. That's why you have a bank alt.
