After some time playing my hunter, i doubt that the T11 set bonus's is worth it.
(2) Set: Increases the critical strike chance of your Serpent Sting ability by 5%
This is a pretty decent bonus, and for sure worth getting.
(4) Set: Your Focus Fire ability grants 1% additional haste per application of Frenzy, your Chimera Shot ability has a 10% chance to immediately refund half its focus cost, and your Black Arrow also deals instant damage to your target.
This bonus is looking to me to be utterly crap, no matter wich spec, but specaly for survival.
