Here is the suggestion based on the reasoning that:
There are maps where the boundaries are literally on top of the objective
Give us some room to play the game
And stop giving the attackers wider area of map, make it fair for both sides
There is a mode where the map is wide open and the teams fight back and forth pushing each other in turn, this is the best setup currently but rarely shows up to play
Open the maps like that on all the other maps, so players can get more value from the maps
Also make the objective much larger. Having so much action on a tiny piece of real estate is just not much fun when it is constantly blown to pieces by everything of the other team. Make the objectives far larger, instead of just one house and 10 metre diameter circle, make it 100-150 metre diameter circle, it would make the game far more interesting to play if this suggestion was adhered to
Make it that teams have to cap and then hold for a period of time before moving on.
