Breakthrough is from the Bungie school of "Let's copy ideas that work in other games and make a crap rip-off". The same school that produced the worst Crucible mode in Destiny history - Countdown-Strike They could have called it Overwatch and put the Blizzard logo on the walls. It has the exact same problems with defender spawns and the games that don't entice people to actually attack the middle. The games I played in Breakthrough consisted of my team taking the middle point very quickly, then proceed to lose because the other team spawned on top of the point they had no reason to leave and camped out because there was no heavy ammo spawns to clear the rooms. The timers in the game mode are absolutely rubbish.
