I do not think that implementing this is too late at all.
Quite the contrary, now there has been identified need for this. Especially because the game player-base is divided by 5 different campaigns?
This means that making the game still busy and interesting requires more effort in this front to push the active players with other players in the active combat with as little bots as possible. This action would make all the combat in the game far more “Lively”.
There should also be an option of “Keep playing automatically” so that you could enter the random game and just keep on playing and twerk/ play with the earned bronze/ silver order cards later once you are done with gaming directly for a while?
This would make the game so much more dynamic?
Of course, there should be an option for “Start from the beginning of the game ONLY” and this would most likely mean longer waiting times/ periods, but it would be just fine for some players who really want that and depending on the timezone/ time on where they play?
In all and all, to conclude:
This actually needs to be done or this game will become slower, more bot filled and less interesting for everyone quite soon?
New players who start the game just see “Oh, this is filled with bots and quitters” and then they get bored and switch the game immediately?
—> Therefore this issue concerns also player base retention very heavily.
What comes to campaigns, only one more campaign could be added in the future.
Some sort of an Asian related theme Japan VS. US/ Britain, however I personally think that the player basis is very divided already and what needs to be done is to push through more and more maps in to the game itself as well.
There are endless opportunities, only for Stalingrad there are:
Stalingrad Outskirts.
Grain Elevator.
Factory area.
Underground Stalingrad.
I touched few other subjects here as well, however my initial support for this idea still stands.
DEFINITELY YES and it should be a preferred option that you can change if you want?
