Had some good games for sure, once i saw what you were doing though, it became too set. I figured my burst would make you go defensive, then defensive and stuns would also help limit your insane burst.

one thing to remember, enhance shammies get two stormblasts per ascendence, it would be hard to deterrence the first one, but if you wait after the first blast 4 seconds or so, your deterrence should block the opportunity for the second. Laying a stack of freezing traps might help, but likely to catch a wolf or get broken. arena 1-4 scattering shot is nice, and if you used that camera centering mod (i think you mod the cfg file) you could probably scatter trap to some degree with all of them vs stacked opponents.

I would also put explosive trap on round robin, each hunter only lays one at a time, so you get 5 knockbacks..

All in all very good stuff, the lack of heals is, i think, your biggest hurdle. though the 1-2 person quick kills without any real CDs is nice.
