If you've already figured out when it happens, what's the point of this question?
If I load my character up in shadowcraft I always get combat ahead of sub, which is not surprising due to my moderate gear level. If I load up Aldriana or similarly geared rogues I see sub ahead by 1k dps or more, also not surprising. My question is where is the cross-over point in gear (mainly agility) when sub takes the lead? If I change my weapons to the P1 legendaries I get almost equal dps estimates, so I know it must be in the neighborhood of 5200 agility.
