Weapons have a bigger market, as Mail/Plate items are only usable by a few classes.
The end of my using mostly self crafted items seemed to go hand in hand with the jump to plate armor at 40. Green Iron haubbie is great for several levels (pre specialization)
Some of the weapons/armor I would've crafted to use if had found the plans at the level/approp time.
Both flavors seem to have a few insanely hard recipes, and the highest ac plate/and hardest to craft, that I have found, is Bind on Pickup!
I am creeping up on bs skill level 300 and there are plans for armorsmith that I would be interested in crafting for more than just skillups again.
