As we all know, muts mobility is its own liability, and blizz refuses to give shadowstep to all rogues cuz it's "a sub thing".
So, what if shadowstep became baseline w/ root breaker and w/o increased damage. And prep takes its place restored to the glory it once had back in vanilla? Now both assass and combat can't take prep no matter the level, while sub still retains its flavor at the same time gives sub one more talent to move around.
I know it makes more sense to post this in blizzards suggestion forums. But I can't since my B.net account isn't viable to NA forums.
