We did highmaul this week. used Aff for the first 6 and it was mostly pretty strong. Used Destro with MF/Supremacy/Cataclysm on Imperator, however and it was extremely good. Between all the cleave opportunities, RoF on the packs while CB spamming into the warmages during intermission, etc, it's definitely a fight where destro will shine. Hoping to get a little more feel for destro pure single target (i.e. Butcher), haven't really done that yet.
