OK, I gotta chime in here. Plain staves are low enough damage as to be pretty poor, I'll admit. But an iron staff is a fine all-around weapon. 140 reach makes it a passable lance (although admittedly more demanding than dedicated lances), but more importantly gives it better melee reach than any other weapon (at least that I can think of from memory). Blunt damage not only knocks folks out, but is doubled against armor, so the 22 base damage becomes 44. Only the Great Ax at 45 can beat that in melee. If you want to trade some of that damage for a shield, you can still use the staff one handed, although you're limited to thrust attacks. It gives you three weapon styles for the price of one proficiency, which allows you to quickly become frighteningly good with all three styles. Finally, it gives you a weapon for all three melee styles for a single weapon slot, leaving you enugh slots to carry a shield or an extra bag of ammo along with your bow. A high end staff is a fine melee choice, for a horse archer especially.
