There are a few fights were combat rogues can use bladeflurry, and it may seem like a single target dps fight, but they're really able to double up almost the entire fight, like protectors in ToES or garalon in HoF.
Can you give us a bit more information though? Perhaps a WoL log? Fights where you're seeing this issue? You're also logged out with your fishing pole on so we can't see your weapons.
