So just straight up a straightforward Hero job. Not some alternate job, not some meta job, just a very classical "The Hero is the strongest job, period." kind of setting. Okay.
Also I see the MC's ego is going to go pretty much unchecked. There is some chance this MC might become relatively insufferable and despite the ten day journey to cool off his head, it still seems like he's in the mindset of this is a game world before it being a real world inhabited by real people. Doubt that'll come up in an important manner though since this is going for the tongue in cheek lighthearted tone.
