Too kind Moot.
"Too kind"? Exactly what about this subject deserves anything less than civil discussion? What, did you get stomped on by an RPG nerd once and now want bad boy forum revenge?
Not one person in this thread, including myself, has taken up the opinion that a full transition to RPG wizardry would be a good thing for AH. So who, exactly, are you so angry at? Troll on WoW forums if you have such deep issues.
And regarding your assumption about character types:
You'd actually be surprised how many people are willing to role play in less desirable roles. I played a RPG once for a few months, got out of it because I couldn't stand the community of teens and RPGish-ness, but nonetheless saw very many people who built up trader/support role characters, rather than the fighter/hero type.
We have this altruistic type in AH currently. You know the guys...they are always willing to run a goon, run supplies, or go pork ords.
