Well I got somewhere between 450 and 500 HKs, I keep very close track since I am closing in on 250k, don't know how you got that little.
Another thing is the server time... When we raid early, we used to get called out by Ilyanah for "not playing when MfD's peak time is". When we do that, we are called out by others for "raiding too late". There's no way we can satisfy everyone's need to die at the same time, that's why we choose our times to do everything randomly, just upon seeing we have enough people online and willing to go.
About the Gurthalak Paladin, there was 1 in the entire raid. We're lucky he's good enough to carry us all (read "spawns enough tentacles").
