What would be a better? Cataclysmic Gladiator's Battle Staff (I currently have) or* Rathrak, the Poisonous Mind (Raid Finder) + Cataclysmic Gladiator's Endgame
are you paired with anyone who uses cc that breaks on damg taken? if so the weapon proc might break it early. whats your resi outside these items? howm uch do you ned the resi from both slots?
I normally do arenas with my friend either on his Feral or Warrior. I'm 4.4k res with the Staff and around 4k with the MH + OH
