I’d like more shorter adventures too.
I’d like more setting books like the Eberron one.
I’d only want more crunch when it’s absolutely needed (like psionics for Dark Sun).
I don’t want to see any more Xanathar’s style books. I’m an outlier in this but I feel like we’ve already got too much crunch in too many different places now. We didn’t get it as quickly as we would have in the past, nor is there as much, but I’ve been feeling a little overwhelmed by it all for a year or two now.
Ultimately I would like them to slow down even more, rather than speed up, and really focus on getting the quality higher. Xanathar’s and Mordenkainen’s were both mixed bags of good, bad and meh for me, and Dragon Heist was absolute rubbish compared to Curse of Strahd and Tomb of Annihilation.
