TL;DR - a team can choose not to play the objective and farm the opposing team endlessly until the timer calls the round a draw. Jumped into Breakthrough curious to try out the new mode and had the experience ruined by a stacked team who were exploiting the fact that they could farm KD and never play the objective. All these did was kill us until the timer called a draw. I have no idea how long it can potentially go on for, I bailed out after 4 rounds of the same toxic behaviour. The game mode completely enables teams to do this and not turn their superiority into victory and ending the cycle of misery. You can easily allow a team to become the hackers one time, successfully defend then never play objective again. Needs addressing.
