Perks for Medium hatchet/sns assassin?

What perks would you go for, for an OPR build?

I am thinking of going with Tumblers and these perks:

5 Shirking Heals

3 Freedom

1 Elemental Aversion

1 Enchanted Ward

1 Hasted Vigor

1 Contagious Upheaval

1 Refreshing Torrent

1 Physical Aversion (forced perk on the Tumbler)

1 Refreshing (forced perk on the Tumbler

Would probably use Ankh, to boost the self heal from Shirking Heals + Tumblers.

Thoughts? Is Hasted Vigor worth over EW/Ele Aversion?
