Coming up with ideas doesn't equal them having a coherent vision. This has been clear since D2's launch (clear since d1 really) and its because this game has a lead dev who has never been in this position in his life. I can give a great example why this game lacks vision. What is the experience a players should get if they play a Warlock over a Titan? What is the play style difference between the classes? What type of players are expected to gravitate to a titan over that of a warlock? It is apparent that the Dev team has no idea. I mean this is the same lead dev who said "We dont know what the Darkness is" in an interview. You just made this game about 3 years ago and you have no idea what the big antagonist of the game is? So, what is the vision of the 3 classes and what effect they should have in combat? From what I can tell the Dev team has no clue because I myself cant find how a Sentinel Titan is supposed to contribute when his abilities are all about a slow slog through enemies in a game where many of your challenge modes are just time runners. Also, if you go back to when Staten was in control, the info being released about the classes was Titans were going to be the tanks of Destiny. That they were the class for people who wanted to play heavy armored damage resistent classes. When Luke Smith came in the only difference is movement and skin. They can all have close to the same states and they all inhabit the same roles with only Warlock and Hunters having some sort of utility through their supers.
