I am sure everyone who has placed CC knows that if your team is about to lose, you can just go on the point when it is less than 1% away from a cap, put your shields up and then just wait for your team to come over. And sure this wouldn't be as big of a problem if overtime wasn't forever, but it is.
It just stands to draw out an already finished game, or worse yet, the enemy team is rewarded for losing, because it goes into overtime, and then they keep on respawning until they have lb and then slowly but surely your team falls apart, then with staggered respawns you can't defend until eventually they cap the first checkpoint and win? Seems a little weird that one person, no matter the class, can roll up with a 90% mitigation, stop the entire cap of a team and then let their team come in and rinse and repeat. Maybe I am missing something here but this just really draws an already finished game out more.
