While I agree that necro'ing makes puppies sad ( and I even heard that Santa kills an elf for each thread ;>) I have to disagree with the account instance lock. I have been able to boost my shaman (lvl 59-64) in HFR until the lockout with an 85 Mage, then log my 4DK-1HP team and run random dungeons for 30-45 minutes.
Maybe it has to do with using only 2 accounts to boost?
You can't get locked out of random dungeons through the LFD tool.
