I'll offer an odd duck choice: Stone/Dark

This combo becomes a beast after IO sets. You can slot for a huge amount of +rec, and wind up with better rec than a WP brute with Stamina (who isn't IOd for +rec, cuz lets face it, that would be silly)

This combo has the best mitigation offerred by any of the AoE combos available. Fault+OG=everything stunned. Just don't turn on OG at fights start, wait till you get fury up.

Pick up Scirocco for your patron- it has two targetted AoEs that are radial, not cones. And fences will prevent all those perma stunned mobs from wandering.

You'll wind up with four AoEs (Tremor, Ball Lightning, Electric Fences, and Death Shroud) plus fault (which you can throw dam procs in) and have top end ST damage available as well.

Just thought I'd add that Air Superiority adds tremendously to this build's survivability. (I know its been said to death, but needed to be here as well) The ability to keep a boss off his feet and not attacking you is fantastic. My boss attack chain is AS, Lunge, Ripper. I slotted AS and Lunge for recharge, and have those as my two single targets attacks (I respecced out of Impale once I got Ripper)
