Could be a DC thing but on Aether when I was on a much more potato PC I would get delayed a bit as the tank and the dps were already off ahead of me trying to pull things. You see that sprint button get hit immediately as soon as the gate drops and people will hover by the exit of a boss to start sprinting out after them. The Aether community definitely wants their daily dungeon roulettes to take as little time as possible and have for years.
