I've had good and bad runs but haven't really noticed a trend towards the bad at all. If anything, it's more trending towards the good, smooth runs. Most people seem to know what they're doing well enough to get through the content without any real struggle, and most times I've given or seen others give legitimate, maturely delivered advice it's been received well. Sure my experience is not necessarily the same as yours, but if you're constantly running into what feels like terrible players and a lack of interest in taking advice, maybe it's your own expectations for what a terrible player is or what constructive advice is that needs adjustment.
