Mar 23rd 2010 8:47AM The amount of sub-par tips I've ever received from 80s were very few and far in between. I don't know, but maybe it's because I could mage port to the customer that made her/him a happy tipper.
10g for all single crafts is what I like to tip others and it is based on my own experience as an Enchanter. Bulk crafting is dependent on how much I'm looking to create, and epic gear crafting is dependent upon how much time or gold I spent gathering the materials. All in all, I always aim to give a respectable tip.
I dropped enchanting a few months ago because I don't like to spend very much time (non AFK) in trade chat. For me, the time it took from whispering people to finally enchanting their gear was more often than not, too long. I wouldn't charge any specific amount in hopes of landing a larger than average tip (10g = average on my server) and I would avoid servicing non 80s looking for service without posting their tip upfront.
