It's too much of a hassle to recruit Minsc, and all your companions are fully setup by the time you do so there is never a place for him in the party. He was sort of "let me try that build with these items as well" type of character. They should've added him in act2 along with Jahiera. I wanted to see their interactions in my first run out of nostalgia, and all I got was some weak banter and a bit of dialogue with nine fingers.
