As of 3.3, Misdirection should solve aggro issues as it now lasts for 4 seconds, unlimited hits, and stacks with other hunters. The stacking is huge for 5x hunters, as all aggro they generate all stack on the same pet. The misdirection change alone makes me want to give hunters another shot at heroics. 5 hunters with 4 seconds of being able to go balls out should generate enough threat. Being able to cast it every 30 seconds and combining it with 5x Feign Death to dump aggro...seems like a tasty recipe to me

From the 3.3 notes:
Misdirection: Redesigned. Instead of having finite charges, it now begins a 4-second timer when the hunter using Misdirection performs a threat-generating attack, during which all threat generated by the hunter goes to the friendly target. In addition, multiple hunters can now misdirect threat to the same friendly target simultaneously.
