I'm not entirely convinced it will beat ShS though, but we'll see. Baseline prep will make things so much easier, though.
On another note, do you think legendaries are worth using over 442 daggers? Idk if its possible to have long matches even if both teams have a healer; if it is, the proc will win hands down.
I know they are for assassination, chances are with the ridiculous mastery levels you can get as sub you'll be able to nuke people very hard when it procs. As we know, burst > higher sustained for pvp.
