if your team happened to be getting completely dominated in a game, would you want that game to go on for another 15-20 minutes?? You could rage quit, or just sit there and slowly watch your team suffer. I've never been fond of either
The feature that has sped up the gameplay most is sprint if you think about it. Players can find engagements much quicker now and move across the map in a short amount of time. If you want games to go longer, would you would have to be willing to give up your ability to sprint. That would go against the control scheme that the game already has in place, so that would probably never happen
Please, if you are going to make a complaint about something, at least understand the issue and have a way to resolve it
