To me the pre-order Bonus in both the Imperial and standard edition is terrible, this 'Play any race in any alliance' is going to ruin the some of the game-play in my mind. I love the idea of the imperial being able to play any race as Imperials as a race are not exactly skilled in anything specific as such which means they are more easily balanced. The PARIAA defeats the whole purpose of having factions since the majority of players will be able to run around in what ever race they want until new players begin to join after all the Pre-order and special editions have sold out.
Obviously it is too late for ZeniMax Online to remove this Pre-DLC, but its none the less a bad move on their part.
