My friend also is a Brawler, The fist wrap type weapons have a low damage output... So with me having a toon that is a weaponsmith I decided to make her a whole range of weapons and go on a killing spree with her lol...
The result was we found that maces seem to be about the best allround choice.... But it still depends on what it is your trying to kill.... I find myself carrying at least 3 types of weapons all the time and switch out if one type aint working well... That just what I found
