Dude, during this time that they've been releasing new campaigns, they've also been updating the game more often than they have in, like, the previous two years combined. There is also no god damn way they haven't developed a pipeline for merging these new campaigns in. So while it might have taken some resources away from other aspects when they introduced support for this way back, saying new campaigns take any real resources away from FMs or ASMs or other features now is a very tenuous argument.

Rather than a new focus, it's just more stuff to get money from.
