Not much you can really do
We have faced trials and danger, threats to our world and our way of life. And yet, we persevere. We are the Horde. We will not let anything break our spirits!"
In my honest opinion, this is the result of Blizz not fixing racials 2 expansions ago.
Alliance and Horde have now completely polarized. With Horde being the PvE faction, and Alliance (IE human) being the PvP faction.
And if your guild leads are switching faction because of racials, chances are you'll follow suit.
Now I'm not one of those Vanilla purists, but that looks a lot more appealing to me that the CC and circle strafe fest that it's become since. PvP has never really resembled the Alliance vs. the Horde so much as it does the Sharks vs. the Jets the way people dance and jump all the over place like juvenile delinquent ballerinas.
If any changes are really to be made to PvP it should be to go back to how that video looks up there. That looks a lot more fun than getting instagibbed while somebody races around you at light speed and you're standing there twiddling your thumbs waiting for their stun to expire.
