1v1? You don't. No class in the game can currently kill a Rogue 1v1, and honestly no class in 8.3 could kill a Rogue 1v1 either, so it seems like that's unlikely to change any time soon.
In all honesty even 2v1 you likely won't kill the Rogue, he'll just leave. Rogues are far and away the strongest PvP class right now, and even more so 1v1. Even if you get the jump no them it makes no difference unless they don't have a trinket and you can stunlock them.
