What is rushing to one person could be a turtle crawl to another. People's playstyles are vastly different. If a person blazes through the game to be "first" and ignores most of the content then you have a point. If on the other hand a person blazes through it naturally/instinctively then it is a playstyle. Sometimes speed is affected by right choices (in rpgs I have a bad tendency to choose the right path unkowingly even when I want to explore) Other cases it's just being too good ( this applies to pve fps) if you don't die on the missions and you go from one to the next efficiently then you are gonna complete loads quicker. If a person who's playstyle is naturally fast holds back on speed then most of the time they will not enjoy what they are doing. Which is against what a game is for. I think when people complain, about no content , they are talking about not enough end game. Before ttk you had 2 raids and poe plus in an Osiris to get endgame power. Now those 2 raids are replaced by one. So where they hoped it would be another endgame activity to add on it became a substitute instead.
