Guess what? You pay for stuff you want, and not for stuff you do not want. Even in a subscription game, you can pay extra if you feel you want/need a sparkly horse. If you do not want to ride a sparkly horse, there's no need to pay extra for it.
You can substitute "ride a sparkly horse" in the above sentence with any of the premium content features, and it still holds true.
