On the armory it seems nobody ever did Garalon HM. Is this an armory bug?
No, it's an incredibly hard boss. No one will ever do it imo.
This. No guild has killed heroic Garalon yet.

No one has killed the "other" LFR Garalon either, so I'd say they're pretty similar in difficulty.

To actually answer the OP :-)
Yes, it's a bug. Nobody in my guild has gotten the kill recorded in the armory, even though we have killed it a couple of times now.
