Hmm, I think they've been doing quite ok in the reports, except for the last quearter, but that probably has different explanation.
I don't see why it would be wasted? You ran it through in a month because you didn't play when they came out and were relevant to your ilvl. The only raid content that is relevant in that context is Siege - and even that relevancy can be debated now that it is 1 year old (it's fully possible to get carried through HC SoO, if your guild is willing).
Kara was also a 15 minute faceroll when you ran it at end of TBC with a guild that had cleared Sunwell.
