Bingo.
Tell an Alliance player you play Horde, it's like "Eh, ok, no big deal."
Tell a Horde player you play Alliance, it's like you just killed their dog.
Which shows that Alliance players aren't really dedicated to their side. They secretly want to play Horde. They show a false indifference to attempt to show superiority over those that feel that it doesn't matter.
Because it does.
If you don't understand why it matters what side you chose, you're an Alliance player, and you suck at PVP. That's just how it is.
Horde players don't feel like you just killed their dog. Horde players feel like they want to kill
your dog. Because they're good at PVP.
Edit: Also, this idea is a terrible one. People always love to switch to the winning side. See common FPS behavior. CS, TF2, L4D, CoD, Quake, UT, doesn't matter. The same thing will happen here, just slowly over time. Not a good move =\.
