Make them immune to injury and death. Instead, maybe a modified KO, with a harder wake-up roll in they get injured.
They are overpriced enough, so their personally apothecary should at least do his job and not wait when the match is finished

Also, give Morg'n Torg Claw, cause he has a frikking huge hand knife. If I'm in a situation when I can afford Morg, then I want to be able to kill stuff.
