You are aware that the Mad Old Wizard is also an aged warrior seeking honorable death in combat despite the fact that age has left him almost completely restricted to healing and buffing (Aka, a support mage?). Also, while a bit irreverent, I wouldn't call him mad.

Just saying, you oversimplify, sir. There are idiosyncrasies within each archetype. The devil's in the details.

The rogue for example, is very overtly rogue-ish, but, he also dreams of being a bard, of playing instruments. That's different.

The Warrior-Sailor is a shrewd merchant and navigator, cleverer than his title implies.
