Ya Ret's mini burst is insane in a stun duration, i almost kill ppl in a stun duration (i even kill DH's in a stun once their blur is active) but most ppl will learn just to kite out outside of ur hoj range :P.
Btw did you notice Retribution buff on yourself when ppl around you died? that buff is so nice in both casual and rated pvp =)))). As always it seems Ret will be a casual pvp hero, now when it comes to Mythic Raiding or R1 push...well we all know the answer
