Yeah, this part really stinks, doesn't it? You are stuck, sorry.
Sony is going to take a beating on this over the coming months, and my prediction is that they are going to lighten up.
I will make a prediction. They will eventually let all players do all skills, but at a "lesser" rate or lesser skill level than someone specializing in it. Or only specialists can make certain uber combines - something like that.
Sheesh, as it stands if you want good bags, good bank boxes, and good spell upgrades, you need 3 diff artisans on your account. And that's a "whole lotta clickin' goin on..." (i.e. Carpal Tunnel time).
Until they make this change (it might take a year), here is a suggestion. In a big zone like Antonica or Commons try /ooc-ing until you get another artisan who has the skill you need talking to you. Suggest you guys do a big trade, like 4 pristine packs for 4 pristine bank boxes. Or a set of armor for several App 3 spells. Whatever makes sense. This will let you avoid the insane prices on the player market. Hope this helps.
Oh, if you can make tier 2 food and drink - don't be too upset. Apparently it helps you regen health and power much faster between fights. When players start to realize this there will be more of a market for it. Anything to reduce downtime is always good. GL!
