My main character(warrior)has mining and enchanting. I levelled with mining and skinning.
I have alts that do alch/herbs, jc/mining, blacksmith/mining and herb/inscription. All these professions except blacksmithing are at max level. My goal is not make loads of gold, but to provide flasks, gems for raiding on my main. Occasionally, i do a clearout of mats that i have excessive amounts off, and can make loads of gold. The last time, i made about 4k. The only thing I need to buy is the leg enchant, and I only buy mats and get someone in the guild to make it.
I am never short of cash, nether do I have a zillion gold, but then what do actually need so much gold for?
I have maintained a cash balance of about 7k for a few months. When I feel like it, I invest in boosting a prof. Recently spent 2k on metal to get blacksmithing to 515 from another 490 or something.
