 PvP rogues are most likely going to be running quick draw, but they also have the option to run slaughter from the shadows. Quick draw, however, allows them to recover back to their target more as their main weakness is going to be getting kited, whereas slaughter from the shadows is going to be way more bursty. The leg rune, most likely they're going to be running between the eyes, as this is going to be their only stun available at level 25. The hand rune, most rogues are going to be running shiv. There is also the option for shadow strike, however, this is only usable in stealth. This allows you to potentially swap to the rune while in stealth out of combat, but you can also swap to the mutilate in venom and deadly brew if you're facing a high armor target. It depends on how the rune swapping is going to be allowed.
