Ok this is a guide/tip for those lazy people who just wanna sit in org or hang out in dueltar all day but still need money for repairs and enchants and such. Well this is pretty much common sense but I was too lazy to profit off it until like a week ago.
Nethercobra Leg armor [50 ap 12 crit rating leg enchant] and Golden spellthread [the healer epic leg enchant] are items that will ALWAYS sell because people will constantly get new pve/pvp pants [this applies to Nethercleft and runic spellthread as well, but they dont sell high enough to really profit on my server]. You DON'T HAVE to be a lw or tailor to make money off these things, all you have to do is buy the mats pay one for their primal nether!
For example: On my server golden spellthread usually sells for about 300g, primal life sells for 15g on low days, so i just buy 10x primal life for 150g, runic thread for like 50s or however much it is from the npc, and spam "LF tailor to make Golden Spellthread my mats +70g [this is what youre paying for their primal nether and tip] your nether pst" and i usually get a reply right away unless its during off hours. So in the end i spent 221g for an item that i can sell in the ah for around 300g. 79g profit for about 5 mins of work, no you can go back to sitting around org all day you lazy bum!
NOTE: obviously if people on your server charge a lot for the use of their primal nether, make sure to calculate how much you have to spend on the primal nether + mats and see if in the end the leg armor sells high enough for you to make a profit!
