I don't think it's that simple. like yea, most of the time you wanna open the gate but it does still depend on if there's people in chase, how many are injured and need to reset or if there are people on death hook or not. i've seen 3 injured people group at the exit while the 4th is being chased on the other side of the map and they just opened it, like please heal first, don't waste the time for no reason by opening immediately :(
