At level 42 I have not developed any trade skills either. And probably
won't unless they become specific to a quest item that I need. I tinkered
with brewing for awhile because alcohol consumption is a fine skill to
master ;) but found that sitting in a city to work up that skill took away
from valuable killing/exploration time. That and I am just lazy ;) Also -
I have always had enough plat to purchase what I need without supplementing
my income with trade skills.
