Importing will allow you to see all the chests on the map. The best way to farm the chests is by using an Outlaw Rogue since they can see whether a chest is spawned or not on the minimap. Other classes will have to get up close and look around while a Rogue can see if the chest has spawned on the minimap. You can use a trial character for this. Just remember to mail the items you get before your three hours have gone.
This farm almost did not make this list. Even though I have had only a little luck with it, it seems to be gathering some popularity in the gold farming community. Although I feel with the recent changes in 7.3, this farm is very close to dying out. Generally what you want to to do is pull every mob you can as you venture to the last boss in the instance. The only saving grace of this farm (if you can call it that) is that some mobs are GUARANTEED to drop greens. Guaranteed. Whether or not they drop profitable greens is a different question, however it's a must-mention quirk you get from running this instance. It also allows you to get your hands on some rare low level blues.
Okay, speaking of pet farms this one is a really unique farm. What we're looking for is the carrier cage : black tabby. This is a very sought after pet for both horde and alliance – which is why its price competitively at 55,000g. The farm takes place in Hillsbrad Foothills on a peninsula like piece of land just northwest of the yeti caves. There will be dozens of stormpike engineers surrounding ballistas that only horde characters can kill. However, that doesn't mean alliance polayers can't do this farm (im alliance myself). All you need to do is to create a class trial (monk is the best) and send him over to the grinding spot. Use the black ox statue to attract the mobs, and easily maul them down group by group. If luck is on your side, you can make out with an awesome black tabby carrier.
Okay, this farm is by far my favorite old world farm. Generally because discovering this spot is like finding a hidden gem that the developers do not want you knowing about. The thing is, everyone talks about farming zul farrack by pulling the entire instance... Nope, the real gold is made by flying over zul farrack... If you fly over zul farrack until you reach the large steps that begins the usual third boss scenario, you will find that there are literally 50 trolls just hanging on the steps and another 25 just sitting at the foot of the steps. It's an amazing scene, as all these trolls have ACTIVE level 40-45 loot tables. Each and every one of them can drop cloth and mogs from the mid level era of items. Whats more is they don't take too long to respawn. ALSO they are not affected by the 7.3 transmog nerf because they ARE NOT in an instanced zone. Making this spot the BEST transmog spot in the game IMO. Check it out in the video, it's really awesome.
Some quests in my guide are marked as "SKIP" and colored in red. These quests are simply either too hard to solo or not worth the XP/time and are skipped. My guide will only list SKIPPED quests if the quest is a direct follow up after completing a quest, not one that you have to click the NPC again to get it. If you hover over the skipped quests, it will give info on why it is skipped in the guide (unless that info is already listed directly in the guide text).
