i have thought about this for a very long time and would also like to see some sort of specialization either for individual crafts or for categories. I love the armory system but the fact that anyone can gather and craft anything and everything is really crippling the economy, imo. Aside from making things for myself and close friends, having all 50 crafts has really not been beneficial to me in monetary value aside from the first two or three weeks after release.

My idea would be to implement this when level cap is raised...like you can choose a craft to level to the new max where all the ones you didn't choose would be capped at a lower level ala FFXI.

I guess a simple quest for specialization would work too.
