So Im an assassination rogue and I dueled a combat rogue last night on the PTR. I have full S14 gear (yes season 14 pvp gear is up on PTR already) and i had damn near full health. I popped his on use trinket and killing spree on me and i went down like a led balloon. Im thinking combat is the next pvp spec in 5.4 if this doesnt get tweaked at all.
