They need HQ and Demolition back, its not the same at boring. and what does it matter about the spawn killing. It is not much different than camping. someone kills you when you spawn while the other kills you crouch in a corner after have ran the whole map. It just part of the game that e have to deal with. it is all.
Or they can add Base Wars instead basically both teams have to capture a point outside of the enemy base then detonate 3 bombs inside of the base in order to win and both teams will be attacking and defending at the same time. 2 rounds at 5 minutes each. I mean I have played every map and this game mode seems like it can work since every map has two main buildings.
They should bring in Hardpoint with the big maps I think Hardpoint would be a welcomed game mode or even Team Defender these maps need a game mode that can utilize these big maps. Just imagine a maniac jug with the flag on Team Defender it would get crazy, everyone ganging up on the jug. Demolition wouldn't be good because the spawns would be random like in MW3, one sided spawns are best for this game mode you might get spawned trapped you might not you just got to play smart or create a spawn flip line in it so if they do get too close then the spawns will flip or you will spawn closer to the bomb. This will keep them off your spawns far enough so you don't get spawn camped, also these maps are big so there will be a low chance that there team would prevent all of your team from getting out of your spawn.
