It still wouldn't compare to Defensive Stance, and it's not too far off from Deadened Nerves + Recuperate during Cataclysm.
Elusiveness is some what useless in competitive PVP because it can't be used when Rogues need it (while stunned/feared). Just removing Elusiveness from Feint, and maybe reducing it to 16% damage reduction -- but making it's effect active all the time would probably make Rogues a lot more viable in competitive PVP.
5.2 addressed Rogue DPS, but not Rogue survivability which is what they currently need.
