All I can say is that I prefer a slower release of splat books and I don't really care about adventure paths one way or another. In addition, given a choice, I'll pick 5E's simplified advancement every time. In fact I do, every time I play.
And many are like you, it seems, and so the game is doing well economically. What kind of books do you want to see in this slower release?
Does that make me a "casual" gamer?
Maybe? As I wrote above, the level of commitment or "work" between sessions is lowered (because of the simplified advancement) and so players can just show up and play, same as with board game group. I have a board game group that is casual and I love it.
No one said this is bad, btw. I'm not using the term "filthy casual." I personally prefer a less simplified advancement, but I'm in the minority. Hence, in my first post, my point that D&D is just not "that game" anymore.
Whether you want more "crunch", more releases, more complex options is fine. Just don't expect WOTC to change when what they have is working better than any previous release.
I don't! What the...? Honest to God, read my previous post: I was telling people they needed to realize and accept that D&D isn't that game anymore.
