Is this a Molten thing? Because Skada was closer to WoL than Recount was in 3.3.5a. You'll see lower DPS numbers, yeah, but that's because Skada accurately tracks "DPS", unlike Recount.
EDIT:
Two other thoughts. If the raid has full BiS gear, then yes, they should be blowing through encounters because it would be ridiculous otherwise. Doing 15kdps in BiS would be dreadful and just as artificially ****ed up as doing 25kdps. Also, the biggest problem in trivializing encounters is poor scripting, not too-high DPS. Most DPS at, say, 264 ilvl is much more realistic, it's the ability to fight a tank and spank version of a boss that makes things too easy. If Putricide were fully scripted, the max creditcard DPS wouldn't help at all unless players swapped to adds and stacked only when necessary.
