It would make sense, a full geared level 60 should have at least 10k - 20k dps....judging he's level 52, he shouldn't be far off 5k I won't think, I doubt you'll make a jump of 8k in 8 levels...that's telling from my brother's experience anyway, he have a level 60 DH, Barb, Wizard and Monk. He refuse to play WD since he hate it xD
