Can anyone actually logically explain why some people would prefer we don't get content? Saying slow down, means just that at some point in time.
Let me preface my points with this: I think you've introduced a logical fallacy that you're driving your argument off of. Saying "slow down" does NOT mean "don't make stuff". The only case it would is if Descent 2E was slated to end after a specific time period instead of after all the quality content has been exhausted, in which case a slower pace would mean fewer items. It's still possible for them to produce the same amount of content, but spread it out over a longer period of time, which is what I think most people want.
Why they want it slower has a couple of major reasons:
1) Many people aren't able to play through the current content fast enough to keep up. And even though there's always the ability to just pick stuff up when you get to it, there's a few things to keep in mind:
a) There's a risk of it being out of print when that happens. Just assuming that there will be enough demand to warrant a second printing is a pretty big assumption.
b) Even if it IS slated for a second printing, it doesn't mean it'll be easily available when you get to that point. Especially when considering expansions, they often sit out of print for much longer than base games before getting a second printing.
c) When playing a game that keeps having new content generated, there's a very real negative psychological effect of feeling like you're "falling behind and will never catch up". Is that better or worse for a company than the people who burn through content so fast and feel like FFG can't keep up with their play speed and risk moving on to other games by different companies and not coming back? Who knows, but that's a whole other can of worms.
2) People are worried that the content is produced hastily with more of an emphasis on cash grabs and content quantity than on content quality. As I mentioned above, I think a lot of people would rather the same AMOUNT of content spread out over a longer period of time (because this game will come to an end eventually), thus keeping it "alive" for longer. This can especially be a big concern of long-time FFG fans who know that the company has a history of releasing lots of different content that is supposed to be able to interact with each other, but somehow missed a full suite of testing and creates even more rules issues than already exist.
There are very logical reasons that some people find that the production rythm is too high.
