fishing. ha!
My rogues working on skinning and leatherworking, and if had been playing everyday i would be level 30 right now, but nooOOOoo. Whats more, youre best getting profession classes that are useful in your favour, either for weapons, armour, or financial *alchemy and herbalism etc to train up and one day sell ultra expension potions, ive seen the prices for some, theyre insane, but people pay for them. its neat.*
For now i will stick with skinning and leatherworking until i can skill no higher in the two.. which will be a long time, or until i have no use for making my own armour etc, which will never cease to be both useful for me and my wallet in the game.
