Picture this, you're the VIP

You spawn and start to make a path to A, being guarded by your teammates along the way, over the course of the game, they start to get picked off one by one and you pick up an AK to fend for yourself, with just one teammate left covering you and 8 seconds left on the clock, you dash from building to building towards A.

In a hurry, you dash in to capture it in time only to see "Contested", said contestee very quickly makes his presence known to you, coming round a door way but narrowly missing you while you manage to hit him in the shoulder, killing him. "Capturing" the objective now says with just 2 seconds left on the clock, aaaand.

"DEFEAT. INSURGENTS DEFENDED THE OBJECTIVE UNTIL TIME EXPIRED"

Why give the players such little time and then give them 0 leeway when they're on the objective? Why is there no "overtime" as long as the objective is being contested or captured like in other modes?

It's a real game ruiner and there was a cacophony of "what the hells?" and "ughhhh" when that happened just now.
