A stretch and too redundant to sell.Yeah, this is a rules update, not just a supplement with additional material. To expect everything to be 100% compatible so people can use both PHB versions side-by-side is a bit of a stretch, IMO. Adventures are a different story.
The changes we see are along the lines I expected. I am not sure I totally like everything, but there are a few changes I expected:
Slow as condition
backgrounds with feats
alert giving proficiency bonus to initiative
actually I think, surprised needs to be a condition too. But maybe we get a better overhaul...
