Yeah, I do my best to order what I want for my ever growing Sorc and in the future other toons even if I can make everything myself, other than potions at this time. You guys fight over them so fast I usually have everything within a couple hours. LOL!
SO DEFINITELY ORDER ON THE MARKETPLACE!
Now not everything is there, but go with the closest and make notes if you want something close, but not listed. =) Be concise in the notes. Usually with the potions, too many are named the same and when I order VR1/50 ones for my sorc I get the best one they know how to make, not the one listed. However, do be encouraged to make notes in that note section to assist in the order if need be.
Even if you can make your own stuff, order it so a guildie can make it for you and get some points. =) Then we will have more people to sell things in the other guilds to make them viable to the public and can keep our main house for us only.
Now if there are people who want to sell but not craft, better chime in with your opinion! so far we are leaning towards Gaiscioch as guild use only for the store.
