I tried 24/15 21/18 using swords and then I joined the 15/24 master race using a steel pick.
I will add this for any new players:
Mold your spec around the weapon you wish to use. Shorter pierce/blunt weapons require less PS to be effective thus allowing you to go more agi based (i.e. more mobility) and longer cut weapons give you more reach (this is invaluable in the big melee situations, though just about every other 2H/Polearm melee weapon will out range you anyway). Pierce/Blunt weapons, I believe, are better for the smaller melee situations.
I have a question for you all. As a 15/24 spec... Steel Pick or Warhammer?
