Honestly, I've advocated exactly this for quite some time now.
People aren't roleplaying advies are they are meant to. They form these ridiculous vast guilds where they organize large mobs (largely with their own free adventurer slots) in order to amass items at ridiculous rates, cast all kinds of magic, and perform espionage.
All the while, the legitimate adventurer game is boring. If you hunt, you tend to get killed as soon as your skills become not so bad. If you gather items, well... that's pretty boring in itself.
I don't think adventurers add anything positive to the game.
Then don't play it until I've had a chance to improve it, which
is on my TODO list (and I have some specific plans).
