I believe a blue post confirmed that the 60 encounter was going away and I'm pretty sure that at least some of the quests were removed a while ago (the attunement ones). No reason why her head and the hunter sinew couldn't continue to drop, though I wouldn't be surprised if the latter ends up as a feat of strength and gets removed. I can't imagine many people still do it.

It's sad when stuff gets removed, but that's the nature of changing content I suppose. Personally I think this is a super awesome way to celebrate five years of wow.

There's just no reason to remove it. Build her an identical cave in Northrend and leave the 60 raid alone. I figured level 90 was when I was going to be able to take my druid back to all the old raids solo and collect the early tiers of gear, and I was really looking forward to it. Like 3 more years worth of subscription looking forward to it.

The main bit i'm worried about is if they break the Draconic for dummies quest, one of the parts of the sceptre chain. Currently the whole chain is working fine and completable (except "bang a gong!" obviously), it would be a shame to break the best quest chain in the whole of the game just so people can see a level 80 Onyxia.
