As a new player, I joined with a group of friends and we all took a crafting profession or two each. Not realising it was a new piece of content, I was assigned jewelry crafting.
This crafting profession is completely and utterly useless to my friends and I. The amount of effort necessary for me to create a passingly-decent ring or necklace is so ridiculous I'd be a fool to do it, considering in a few levels they'll loot something better!
I'd say, don't punish new players and make it next to impossible to make decent green or blue equipment with traits. I'm not trying to create crazy-strong gold items or even purple.
I feel like jewelry crafting should be comparable to the other crafting professions.
