I miss the times when a niche hobby didn't need to control their press like a multi-million dollar conglomerate...oh wait. These press releases have gotten pretty bad in that regard, which I wouldn't be too bothered by, but I don't see much elsewhere, where a more substantive conversation can take place.
During the video, there were a few times it seemed like they were talking out of both sides of their face, but that's nothing new and it is a playtest I suppose. It's a advertisement, where I'm more interested in talking shop.
It's possible WotC thinks a lot of their feats were half-baked, and were either never used or broken, so they're revamping them. All while they have consistently said that most tables don't play with them.
