I don't have a balance problem with this weapon (though some might), I'm just confused by the reasoning behind it's category and stats. AFAIK, it's just a big, metal-shod club. Not sure why a big metal club would get a x4 crit; most of them have been piercing weapons to date. I'm even more confused by why it's an exotic weapon - seems to me that if you can use one club, you can use them all? Doesn't seem like there'd be a lot of subtlety or special training involved.
