If Stopwatch is going to continue to exist as it does now, there needs to be a change in the timers.
Currently, there is only one timer, and it's the overall time remaining. This makes sense for the first round, since a team has 15 minutes to do everything, however, for the second round..
There has to be a second timer, called Threshold. It will show you the actual time you have left to complete the objective. For example:
Team 1 pushed the EV to point X in 15 minutes. The EV moves at a certain speed. For this example, the time it takes for an unhindered EV to be pushed from the repair point to point X is 90 seconds.
This means that if Team 2 doesn't push the EV at all from it's start point, it's impossible to beat the other team if the timer is under 90 seconds. The Threshold timer will show this, and update in real time. If the Threshold timer runs out, you lose automatically. So, as the team pushes the EV, the Threshold timer will increase since the amount of actual time it takes the EV to move to point X will be shorter and shorter.
This works for C4 timers too. Since there's no OT in Stopwatch, the amount of time it takes C4 to blow from arming needs to be taken into account. If C4 takes 50 seconds to blow, then Team 2 has 15 minutes minus 50 seconds to arm C4 to win. If they don't have C4 armed by 14m 10s, they lose. Or, if Team 1 disarms C4 with less than 50s left in the round, they win, since it's now impossible to arm AND blow C4 before 15m.
This will also add a more visible level of suspense to the game. With the threshold timer accurately representing the literal amount of time left, players will be more aware of the time limits in the game, instead of suddenly realizing it's impossible to win from this point and losing interest in the rest of the match.
Good idea? Bad idea? Shitpost? Pro MLG?
