The tradeskills that *match* with certain classes are very flexible in EQ2. For example, it would benefit any class to be a Provisioner.
I guess there could be an issue with weight for some of the caster classes so maybe you would find it annoying to be a Carpenter constantly lugging heavy strongboxes.
As a Wizard, would be cool to make your own spells, and Swashbuckler could make poisons or armor for themselves.
Just some thoughts. Other people might have different ideas about this topic.
