Yeah, I rarely took Minsc out and didn't feel like I was missing much. I'd talk to him in the Elfsong most evenings and hear any updates to his thoughts, and I got all of his background, and that was fun; but rarely actually had him in the party. Except that I specced him as a gloomstalker ranger, and used him when I wanted a max stealth party.
Minsc has some really funny banter when you have him in your party. Well, if he align with you humour prefrences that is, I know many don't find him funny.
