I think they couldn’t cope with 4 campaigns anyway.
But they decided to add two more new ones, because of this they completely stopped updating the old four normally.
For the last update, we received in the old campaigns only one really new level in progression (mortars in Berlin), the rest is only CTRL C + CTRL V. Well, a large number of premium squads that all have new weapons …
(There’s no point talking about maps, only 5 new ones, and only in Pacific)
Speaking of premium squads, they cost a lot of money, but nevertheless they are common (you can often meet a player who bought these premium squads only in one side in one campaign for $ 300 (conditional price), so the game should be very profitable, and you should have enough money to hire more people, because now either your team is lazy and stupid, or it is not big enough.
I think if you decide that you can have 6 campaigns at once, then you should update them normally.
Again, 1 new thing in the usual progression and zero new maps for old campaigns for almost half a year is very little.
Anyway, this is just my reasoning. I don’t call\order anyone to anything.
