An easy way to look at it is as following. Which have been the most requested races from the previous expacts?
Now, look at who has gotten most of the races they wanted.
Fixed that for you. Mag’har were asked for as a customisation for existing Orcs, and even then, it was a fairly muted request.
That never happened. The Horde player base were just as surprised as anyone else.
So actually, the Alliance got one thing they did ask for, the Horde got one thing they didn’t ask for.
Just sayin’, if you’re going to try and play the bias card, get your facts right. Horde got none of the things they asked for, Alliance got one of them. Stop trying to play the victim. It does not help the High Elf cause look mature and measured…
