I realized that its not worth it anymore.Yeah it was a good waste of time at the start of cata but now it is boring waste of time I've farmed and made 90+ troll artifact no sword and right now it feels like a pain to farm.Like a home work you dont wanna get even close to it.
Think about it,it will be trash with new tier and you can get similar weapon from pve or pvp.Magmaw drops 2h mace and pvp weapons are easy to get.I guess you can get em with 15+ arena wins.So i just gave up farming it.Gonna get the weapon from magmaw or if it doesnt drop this week i'll just get a pvp weapon.
If it was a heirloom 1-85 weapon it sure would be worth to farm like this and i think blizz should make that weapon a heirloom not any item that will be trash few months later.
