That's a very roundabout way of saying"Everything stays the same, except instead of creating four crests in your inventory, you now buy one from a vendor for the same price"
Honestly the whole "need enchanter" part is annoying, you should just buy a token for currency.Enchanters can provide a material needed for gear - but that should be on the AH - not an extra step to jump through.
Dracothyst comes from alchemy, the supply is limited by transmute cooldowns and you need 300 Zaralek Glowspores which is farmed in old content. So this is a feast for gold goblins, and I recommend to farm Zaralek Glowspores yourself and let a friend alchemist transmute it for you.
tbh as an Enchanter/Alchemist main, I'd rather play the game than sit in Trade Chat spamming "Enchanting Crests" all day. I'll do Crests for Guildies and Alts, but that's it unless I happen to be in Valdrakken and happen to have the nightmare-scroll that is Trade Chat open.For casual crafters most of this Craft Order system has been a total let-down with the disconnect between buyers and sellers outside of Guild. As a buyer, I'm lucky enough to have the Bruto, but having to run to the AH to get the mats, rather than integrating with the Auction House, is a PitA.Having no limit on Personal Orders, other than availability of mettle (for some crafts) and Dracothyst (which can simply be bought from the AH) means that only the Goblins can make good gold from this system.
