Sounds like this will very much be in the vein of “5.5” plus adding some digital tools that look pretty cool, though I have very little confidence in Hasbro getting it right.
Here’s a direct link to the first batch of playtest material for anyone curious. My initial takeaways are that it allows mixed racial backgrounds easily and there’s a much greater emphasis on feats than 5e.
Well, I think DnD 5e is one of the worst systems for GM support. Sure, the settings books have some cool plot and fluff, but the prebuilt campaigns are widely panned for not having good GM resources, and the settings books similarly lack a lot of guidelines, and just overall 5e is regarded as pretty hard to run and to get into GMing.
Older editions of DnD, and most DnD rivals, have better guidance on how to actually run game, how to actually construct challenges and build encounters. I've heard it said that 5e is built to sell books to players, not to GMs, and I strongly agree.
