I guess I don't understand the build, it's 0 AE, besides piranha which isn't really ae damage anyways. The dogs blow up but I would hardly say that's a damage dealer.
Maybe your F&R is making Haunt do insane single target dps?

I don't think this can scale as well as other builds is another concern, but interested to see!
Was close ot getting 6 piece harvester on all, and was planning on running jade to farm for items. I think other classes deserve a shot though instead of trying to "make" this one work.
