funny but... since it need good dmg weapon HOTS isn't that good, the CB/DS/proc are really AWESOME... but no ed... so nice for smiter, or kicker but not that goood for flip imo.
for survivability ias and life/h seems to be a nice thing. Still depends what you mean by viable, and for which runs . It can be really tanky for sure but dmg is another thing. i did several tests, without enchanting of course didnt wanted to invest in a fun char, (i dont even got full enchant in my only/main char).
