If I were to design the next edition of D&D, then it would look somewhat like 5E, but would incorporate the changes enumerated below:
1. The collapse of saving throws back into will/reflex/fortitude.
2. The inclusion of the Mystic class (preferably renamed the Psion) in the standard class array.
3. The "propping up" of feats. This works in conjuction with a few of my proposals that lie immediately below.
4. The collapse of the Fighter and Barbarian into one class with subclasses and sub-subclasses.
5. The collapse of the Ranger and Rogue into one class with sub-classes and sub-subclasses.
6. The collapse of the Wizard and Sorcerer into one "arcanist" class with subclasses and sub-subclasses.
7. The inclusion of more detailed weather rules.
