Re: ww barb sword or axe?
are we talking PvP or PvM?
in PvP axes are generally chosen because you can't make a Beast (the standard off-hand weapon for a bvc) in a sword, however Grief can be made in both.
the main exception is a BvB, which uses a shield. a Grief colly sword has much higher minimum damage than a zerk (but getting a really, really good grief colly sword isn't easy. you need 39ias AND a good damage roll)
if it's PvM, use whichever you prefer, they'll both work just fine.
