In regards to the video...what's the point in this: "Agnes was almost in tears telling us how they've had to split the update and delay part of it. The Sims team would never. And that is a massive part of the problem with Sims 4. Laundry Lists are not communication, they are a joke." ??
I agree that Laundry Lists are pointless and illusory, but Maxis doesn't need to give us any more raunchy videos and it's not a massive problem, that would more likely make it far worse in fact, as demonstrated previously when @SimGuruLyndsay tried to communicate.
At this point I frankly don't even know what kind of communication, you OP, would want. They won't and can't announce packs in advance and if it's about bugs, I can't imagine how they'd explain debugging an almost 7 year old game made in python to a bunch of people who barely know how to type on twitter.
What TS4 needs is either a bigger team dedicated to quality control and debugging or that it's packs are given more time to be better developed and integrated with other packs. But as stated previously, we are looking at an almost 7 year old game....would that make sense at this point? I guess it really depends how much more time EA is willing to have TS4 on life support, it obviously gives them A LOT of profit.
