Yeah, generally I will minmax a bit, but I do try to bear in mind the character themself when I design them, so I'll try to organise stats optimally, but pick thematic spells, for example. I have fun not dying, but also in having a character that makes sense to me
Which makes it so fun to dm! I had someone make basically a batman character, but it was a min-maxed goblin shadow monk. Who thought he was a great investigator but wasn't, which always was funny to have a dumb batman trying to insecurely inserting himself into situations he shouldn't. He didn't meditate, he 'brooded' and was only technically useful in stealing/combat or when wisdom was in play. So at the campfire he'd be able to console the warrior for losing with the wisest thing that character has heard, only to follow up with something extremely dumb immediately after.
