Frame rate is not a factor of tje game's quality. Remember, when you push for framerate, you compromise some functionality. That is the reason dark souls 3 only runs 30 on console. Even at 30, my game freezes every time I fight the dancer. The main reason 60fps isn't practical in destiny 1's life cycle is programming. Framerate isn't just a graphical tune up like most people believe. Almost everything in the game is run through frames. Your character speed is a function of your position, by frame. Every timer is tracked by frames. In order to change the framerate on a game that's already been programmed, you'd have to rework everything that's part of a sequence, has an animation, or is controlled by a timer, which is just about everything in a game. It's possible for dark souls 3 because platform-delendent framerate was something they had in mind while building the game from the ground up. Even if they managed to make destiny 60fps, there is still the question of functionality. So no, it's not unacceptable, despite what you think. The "this game does it" argument is invalid here.
