We generally (outside of a few outliers) have class balance sitting at a very good level right now. So realistically, they don't have to touch balance at all, outside of tier sets.
The "Blizzard struggles with balance" is kind of a self-made issue because they insist that players just can't play the game if the class stays the same between two expansions, resulting in extreme changes every expansion and having to rebalance every class.
Well, Hero Talents solve that. You just need to balance that talent set, and that's it.
So for Midnight, if they decide to add more Hero Talents, they don't need to rebalance every single talent tree in the game, nor do they need to rebalance the TWW Hero Talents, all they need to balance are the Midnight Hero Talents so they are in line with the older ones.
Once again: Dark Ranger would stay exactly the same between TWW and Midnight. It's just in addition, you can pick Void Hunter, so you would have to pick between 3 rather than 2 hero talents.
Any balancing issues stem from Blizzard trying to reinvent the wheel every expansion.
