It's not about feeling somehow less special because power level is balanced, rather all classes play the same in a general sense. In 3e, if all you wanted to do was bash down the door and kill things with your pointy stick, you could do that no problem while your friend spent 20 minutes figuring out which spell to cast on their turn.
But is your friend getting skipped for 20 minutes, or are you waiting for 20 minutes while the DM stops the action so that your friend decides? That was one stated problem in the gap between 3E and 4E.
