The problem is that Wizards of the Coast’s support of D&D is the worst that it’s ever been, except during the days when D&D 4e (2008-2012) was dead on the vine… All told, D&D saw a scant five releases in 2015…
This definition of “support” was one of the issues I had with the otherwise awesome Designers & Dragons. Does anyone really care that WotC hasn’t released slabs of splats for 5e? Do 5e players feel “unsupported”?
I dunno. I’m not really focused on 5e, but the lack of splats and focus on adventures feels refreshing.
(I owned almost everything WotC produced for 3e. What little I used generally didn’t work that well, and I ended up selling almost all of it.)
