Yeah, I have the Highmountain kite. That's how I died this morning: jumped off of Highmountain to attempt to glide to the falcosaur spot - but failed to be over open water when that timed out, so go go night elf +50% corpserun speed! Something similar happened a few days ago, too.
I never played the expac with garrisons. I tried to stand up Thana's, but I gave up because it was way too confusing. But that's interesting that they're still relevant, hmm.
