Surprisingly, I not only found a group, but found it pretty quickly. But that wasn't the best part. The people were.
I didn't run into a single rude or "go go go" type person. No one complained about gear except for one brief mention of a tank's gear, who had a grey belt, but no drama come from it.
We had mistakes and bad pulls. People died. But no one whined or raged. Why?
They were all people who wanted to be where they were. They could get more xp and better loot in LK instances. BC randoms don't even give points, just a bit of gold and bonus xp. They would only go there if they actually wanted to run BC heroics. Maybe it was for achievements or to see what they hadn't seen before. Maybe it was nostalgia. Maybe it was for something other than the same three or four LK randoms. Whatever it was, the basic fact remained that they were not in places for some quick external reward, but for something in the instance itself.
I'd never tried this before. I didn't even know it was possible. And that may be the problem. People will run lower-reward, higher-fun (subjective, of course) content, if they know it is possible.
Maybe the most important thing I learned from this experience is that even with the anonymous cross-server grouping, putting like-minded people in the same place is possible and yields a better experience. But I already knew this!
My mage is now level 63* and has never been to Outland... He's found a handful of groups, most of which were populated by players above level 58. That means that players who could be running Outland for bags of useful items, higher xp, and short queues, are instead specifically queuing for older instances. There are players specifically choosing older content with fewer tangible rewards (in a virtual sense)... Players are specifically choosing to run these instances and are exhibiting unusually high levels of patience for pulling speed and tolerance for wiping... I have to give some credit to the cross-server group-making tool. Without it I'm not sure there would be the population needed to form groups at all.
This was the mage who, well here's the start of an earlier post
In the past I've complained about people skipping content with the obsolescence of every raid that isn't ICC and heirlooms to speed through leveling. I decided to go a step further and do that to an entire expansion of content.

I think I might do this again on my next mage (she's the one I talk about earlier in the post). I don't like Seahorse Land much, so if Hyjal doesn't tick, that could be my plan: run BC randoms until they run out, then run LK heroics until they run out.
