New maps to be offered to all game types

It is nice to see that updates bring new maps and changes to existing maps however, I like to play the Kill Confirmed mode and have not really seen much of the new maps and wonder why it is that it has so limited amount of maps offered in gameplay. Looking at other gameplays’ like team deathmatch there are so many more maps offered there and it makes no sense why that can not be the case in Kill Confirmed.
Does anyone know the reason why that is the case?
I am starting to get pretty bored of the current availability of maps and am thinking of switching to a different game all together just to have a change of scenery.
Give my your thoughts on what you think of this.
