In conferences with guys who are 1) enjoying themselves, and 2) talkative, it's not a problem. Attributing it to the format change fits the "I told you so" narrative of change is bad, but it doesn't really describe what is happening. Chat is prominent, more prominent now than it was before. It is not hard to find, or understand. It takes no more clicks to chat than it used to, unless you are trying to access it in the roundabout way because that's what you've always done. What's happening is a lot of conferences have been hurt by attrition. Fewer players is probably going to mean less chat. But in conferences that are still healthy, it's less likely to be an issue. Go poking around in any given world, and you'll find conferences filling up lots of chat pages every season.
