I feel like Bungie took two steps back when it came to making us choose between the two paths in our subclasses rather than letting us fully customize and personalize our character and playstyle.

How about we ask them to add a third tree in the middle. Extend it like the one from D1 to allow for more customization. When in pvp activities the top or bottom tree is active, depending on which you have selected. When in pve activities the middle tree is active. This could add depth to the classes and maintain pvp balance.
