I went all in on the Hedwirg meme using his premade 32 point stat buy and going full shield bashing fighter and it's going a lot better than I thought it would. I guess the only downsides are AC because armor in KM is objectively worse than pajama tanking by every metric and the fact that flails are kind of a shit weapon group with the only good flail in the game locked behind a late game quest, though you can cheese it early on.
