One of the biggest disadvantages of using leatherworking WoTLK Gold is that it can diminish in value once an shaman hunter reaches the level of 40 as they'll be able to change to mail at this moment. This is a bigger issue for shamans rather than hunters, since they'll be more focused on the stats bonuses to their equipment, instead of its abilities as armor or armor. Shamans, however have a need for as well the more robust armor of mail and the stamina and strength bonuses that can be available on this type of.
Mining is a collection skill that is compatible in the two skills of Engineering as well as Blacksmithing. Before you can begin mining it, you'll need an Mining Pick (which you can purchase at any retailer of trade skills) Also, you'll have to develop your mining skills to at least level 1. You can then go out into the world, and begin seeking out mining veins that will allow you to find precious metals.
It's impossible to tell which mining veins you'll see.
Metal will typically be discovered in veins close to mountains and hills. It will rarely be seen in the open spaces of an area. That means that collecting metal typically requires more commitment than the skinning or herbalism. It isn't possible to make your own resources by killing animals, like you can with skinning and you won't be rushing over your resources as you travel through the majority of the zone. You'll likely have to devote a portion in your day to "mining runs" or "mining runs," and then run WoTLK Classic Gold through areas where plenty of metal veins are thought to be.
