From our most recent raid on Tuesday.
Also swords are more dps mathematically than daggers. Not even taking positioning into consideration. Not to mention the difference in scaling once you start looking at haste gear later on.
Rogue pvp is meh at the moment. In high end 5v5 in arena's we definitely need some help. 30/0/31 daggers is now really bad for high end PvP. You would actually want to consider combat maces for the stun effect. The reason behind that is daggers rely on soo much crit and with resilience its horrible. Most good PvP'ers actually have upwards of 400+ resilience now. That's a huge reduction. I only pvp now just to get welfare points and pick up cheap weapons while I wait for them to drop in raids.
