Right not on my server a stack of embercloth goes for about 100g. One stack of ebmbercloth only makes four bolts of embercloth. Add that to the cost of purchasing volatile elements and it gets pretty expensive leveling up skills. I think a stack of savage leather costs 110g or so.
I meant more like class skills – Frost Nova, Death Coil, Storm Bolt – than professions. I’d sau professions are only slightly more useful than gold. They give a buff, but unless you’re doing seriously close to your theoretical max damage, you’re probably better off just practicing than sinking all that time to gain 80 more agility. No real use at all in PvP.
Nope, people don’t just buy “gold” off farmers. Often what they pay for is playing for them: speed leveling and obtaining already-existing “experience-based rewards” (in WoW this is a matter of doing certain tasks for several days, where “several” can range from five to over a year).
