IM a lvl 83 IK barb and do some decent dmg, (i think anyways) I'll tell u what i do
2.3-3.8k reg attack dmg(before MIGHT and Charms)
2.7-4.5 WW dmg /w ww at lvl 28(Before MIGHT and Charms)
AR is 5.5k

I recomend getting some 30-40ed jewels and putting them into the maul and armor or helm to up the dmg done, there cheap and easy to find. Also Get a ACT 2 NM Might merc for extra dmg, and some
poison/fire/cold/lightning dmg charms and such. Also getting some combat or mastery GCs can help and they seem to be the cheapest of the skill GCs.
PVP blows unless ur 10-20lvls above your opponate LOL PVM is ok, in hell baal takes forver and meph dosent last too long so you should have fun with this build. Its cheap greasy and a change from the EBOTD wielding barbs and uber-item chars that cost insane amounts of money to make.
PS the set cost less than MAL u can get the set for a UM and a bunch of Pgems Armor is the most costly piece of this set and can range from UM-IST or a bunch of decent items to get pending on the loser who has it
