Need help on Assassin armor combinations.

I currently use a full set of Shrouded armor (+7 energy),
I've heard people saying that for the Chest Piece it is recommended that you use the one which reduces blind duration.
Should I change my chest piece or not?

Its alot on personal preferance. If you think you need the +7 energy to do the combos that you like then stick with the shrouded. What alot of people do is put nightstalkers on chest and legs and shrouded on hands and feet. I know viper likes his shrouded for his extra energy. I personaly do the nightstalker shrouded combo. Its all what appeals to you. If you think you are spending years blind then get the blind reduction
