When you went to the blizzard store you were able to change to horde at the time, so in say a week if they make alliance racials more powerful there was no bait and switch. you made a choice to go horde when the opportunity arose and now they can decide if they wish to go allianceBait-and-switch is a form of fraud used in retail sales but also practiced in other contexts. First, customers are "baited" by merchants' advertising products or services at a low price, but when customers visit the store, they discover that the advertised goods are not available, or the customers are pressured by sales people to consider similar, but higher priced items ("switching"). http://en.wikipedia.org/wiki/Bait-and-switch

It is not just the racials tho, as mentioned due to the high amount of top raiders that made the decision to go horde many raiders also went horde due to the amount of players able to raid and having a larger recruitment pool to draw from.
Now you say racials are ok and only effect a small minority of the playbase, well that small minority effects a much larger plyer base then the racials themselves.
So we need to attract the small minority back to alliance and then hopefully a few of the larger playerbase will also follow suit.
