Playing with Yet Another Hunter the other day, I was running around the Eversong Woods when it occurred to me that here's an Alliance equivalent to the Horde problem with owls.
See, hunters in WoW can't tame an animal to be their pet unless their level is equal to or greater than its level. Before 40th level, the only owls in the game are the ones that fly around in Teldrassil, the night elf starting area. This in and of itself isn't so bad, as characters enter enemy territory on a reasonably regular basis; what makes it awkward is that getting to Teldrassil is an immense pain in the ass even for the Alliance. First you have to get to Ashenvale, which is a long thin zone with only one outlet to the rest of the world, and travel most of its length; then you have to go into an Alliance town (with guards that attack Hordies on sight/detection), wait for an Alliance boat to cross the ocean between the mainland and Teldrassil--if you are Alliance, you can take a "taxi", and if you're a night elf you don't even have to pay for it, but Hordies can't talk to the flight master--and then get past the guards to a teleporter...that plunks you in the middle of the night elf capital city. The existence of the draenei homeland, which is accessed by the same dock, adds similar possibilities (if any of the draenei area critters are unique; I know not).
I've done it twice, with Tauren hunters; both attempts involved dying at least 25 times1. But there was no similar thing for Alliance hunters; there are unique critters in various Horde-controlled areas, but none of those areas are as sheerly annoying to get to as Teldrassil.
But now that I think about it, the blood elf homeland just might be; it's way up north, on the other side of one of the highest-level areas in Azeroth, and there aren't any Alliance areas as close to it as Ashenvale is to Teldrassil. And it has panther-like cats in colors not found elsewhere, and the big bird/lizard flying things for those who want a really distinctive pet. I must think about this...
1: Though I have just now realized that there's a way to get onto the boat with only one death: swim around the town to the end of the appropriate boat dock, then drown yourself and run your spirit back out to rez on the dock. You're out of range of the guards at the junction. Getting to the teleporter is still a pain in the neck.
