Well, Ive gone from 1-40, and raised alot of money with Herbalism/Skinning.
I bought my mount, bought some armor, and trained, im at 42 now. I stand at 30gold, and im going to raise 70 more.
Then, with 100 gold, i was thinking that i could drop herbalism for leatherworking, and take my first crafting profession. And use the 100 gold to buy lots of patterns.
But i have a question, can someone make money with leatherworking?
