@TNT261 - the higher versions of "Carrier" job also have item bags, but they look different.
But you're right - carrier is a good addition to any adventuring party. Even in Danmachi, where the MC was a solo adventurer who didn't go far from home, he found a carrier to be a useful addition to his team.
The country doesn't seem to be good at dealing with bandits, though. Is it because gods give out "bandit" jobs?
