I'm pretty certain that they will impliment another way to unlock paths but they are taking their time to release it. Just like they do with everything, like orbs or Dokkans for characters that then make events easier to do. I think it will happen any way in due time.

If they have decided that the only way to unlock a path is with a character then they will have made a very strong decision to never change that. Money or gameplay progression reasons.

Personally I think it is on the way, but if they  have decided that they don't want it in the game then they won't have it i believe.
