Euhm if nobody farmed the mobs for the materials do you think prices on the market are lower or higher? You know supply and demand how it works?
What is your problem that people farming them? I farm them a lot too, i just pull them to me with aero and then nuke them down with holy, am I a bad person now? I use them mostly for crafting so then it is ok that i farm them.
I mean i farm them for my crafting to make something i then sell on the market to make money. So what is the difference if someone else farm them and sell the items directly to make money.
Stop bitching about it, really sucks if you need the materials but you think prices are high cause everyone farm them while that isn't the issue.
