Enough with the new Subclasses/Feats/Species already
News about the Arcana Unleashed sourcebook is all over my algorithm right now and it got me thinking. WotC's marketing folks must have convinced them that the community wants lots of more subclasses and feats and species and other character options. Personally, I think we have enough of those. I'd rather they went back to putting out adventure modules like TSR used to do.
I'm a module runner as a DM rather than a homebrewer. I loved the old modules and module series. Queen of the Demonweb Pits, Against the Giants (G1-3), and so forth. Even when I started with a homebrewed setting I relied on lots of drop-in, one-off adventure modules and pre-written encounters to fill my sessions. (Thank the gods for DM's Guild.) I love those short (30-50 page), self-contained adventures that can be dropped in anywhere. The Adventurers' League content is pretty close to this, but, for me, suffers from poor implementation.
I think WotC would be well served to start putting out new modularized adventures rather than simply piling on the character options. The Forgotten Realms has a whole continent East of the Sword Coast that hasn't had any new content since 3.5e. The lore that we can access for those regions comes from either the novels or the early modules. I'd love to run a campaign in Eberron, but there are no, or very few, published adventures for it. Even fewer for Ravnica, Theros, and others.
EDIT: Thank you to everyone who responded. There is some good discussion here and some good points made. I understand that the market is better for player facing content. Also, I don't really want full campaign books that take you from levels 1 to 13. Those are not modules. Those are campaigns. All I want is simple drop-in adventures, maybe a level or two. I have run a few of the full campaign books, Strahd, Dragon Heist, Mad Mage. Those are fine for what they are, but I think it'd be nice to see short little adventures that I can drop in wherever. As at least one person pointed out, DMs Guild is great for this. I have run several adventures from there, especially those by DM Dave and MT Black.
