I apologize if this question has been already answered time ago, but I didn't follow MtG so close at the time of the release of Commander 2014. I know that in that set there are five planeswalkers commander, Nahiri, Daretti (who don't present particular problems, since they are now neowalkers, even if Nahiri started as a oldwalker), Ob Nixilis, Freyalise and Teferi. When these last planeswalker are portrayed in the card they are still oldwalkers (immortal, demigod, immensely powerful) - if I'm not mistaken - so how is it possible that they got to be represented on a card? I thought that all the meaning of the Mending was to cripple that oldwalkers immortal stuff to make them playable. But then we have some oldwalkers who got their card! So, has MaRo said how this was possible? Teferi and Freyalise are here represented during Time Spiral, so when the Time Rifts were in some way disturbing their power? Or they didn't explain the flavour behind this decision? If so, they could in future make Serra, Urza and other oldwalkers card?
The flavor of Planeswalker cards is that they are giving you some help, and the loyalty counters represent how long they're willing to stay. They aren't representative of the characters overall power. Because of this, oldwalkers can be printed as Planeswalkers, with the understanding that they're not using their full power to just win the battle for you.
A good example, flavor fully, is during the Eternal Ice where Jaya summons Freyalise and they negotiate for what Freyalise will do to help.
