I just want to point this part out. It's always interesting how people try to minimize alliance losses (especially night elf loses) while blowing up horde losses. Teldrassil also contains the city of Darnassus that would be the equivalent of Undercity. The horde destroyed Undercity but are reclaiming the zone, the entire zone of Teldrassil and everything inside including Darnassus, Shadowglen, Dolanar etc. is lost entirely. Not only that the night elves had full control of Ashenvale after SoO but as of the exploring Kalimdor book, the horde is back to having many areas under control again, and the horde aligned shatterspear trolls have popped up again in Darkshore, so the horde gets new control in Darkshore. Darkshore is also blighted and devoid of life in exploring Kalimdor.
If you are going to make these arguments, do it a bit more honestly at the very least.
That is why I said playable races, you can say like Quilboar have been the punching bags since day 1 as well, or whatever race that was designed to be a non faction aligned enemy.
