LFD "random" heroic problem

[Multibocks]

When my tank queues he always gets Stonecore. I hate that fucking instance, can't get puggies to not die for the first two bosses.

Small update:
Wednesday: 38th queue was VP
Thursday: no random heroic VP or SFK, so no Valor Points
Friday: 38th queue was SFK
Saturday:
I've leveled a toon to 85 without discovering any cata dungeons except of VP (so all I can get is SFK, VP and DM). Tried to queue 4 times and got 3 DMs till SFK opened. Will have to test a few more times the next couple of days. Looks promising so far, but it could have been pure luck for today.

(and yes, 38 queues = about 10 hours of queuing to get a 2 out of 9 dungeon, LFD is f'ed up)

Last update: Queued 12 times so far using the toon with only 3 possible cata heroics. Got 6 Deadmines, 4 SFK and 2 VP.
