[Dreadnought Stun Blast bugged?]

Whenever I use the Stun Blast skill I am losing about 500 HP.  No where in the skill description is it listed that this skill uses HP.  

Anyone else have experience with this.  Or does @Juji / @Hime know anything about this?  I dont recall it doing this prior to this last update.

[Warlord/Dreadnought build ?]

Does anyone know of any current build listings?  Or at least what a solid Dye setup is?

Cant decide if i should go +Str +Con -Dex  OR +Str +DEx -Con
