So the ASI issue is being rehashed again.
I'm on the record wanting the fantasy species splats to define the species, PCs included, and I want the species to actually have different ranges of abilities just like they have different traits. And no, this is not any more problematic than the wood elves being faster runners than the dragonborn. I also want the ability scores to actually mean something in the fiction.
But I also understand why floating is favoured. The game is built so that the classes very strongly encourage you to max your main score, so playing a species that can't do that might feel bad. The ideal solution would be to lessen this pressure, but I doubt they're going to do that. I feel the current situation is unsatisfactory even besides the species issue. The class dictates your ability scores. Every wizard of given level will have same int, every rogue the same dex etc. At least some martial classes have reasonable way to spec into dex or strength, there should be more stuff like that.
Overall, I am a bit meh about the changes. They seem rather insignificant. I don't see them fixing any major issues and feat balancing remains wonky. So it's just a bit... I don't know, I'm not hating it, but I'm not really needing any of this either.
I guess the classes are the real test, as those are the main crunch component. If they can make significant improvements there this might be a worthwhile update.
Also, I'm somewhat worried about the apparent move of most things to the long rest, that's the wrong direction. I also don't like the autofail on one and autosuccess on 20. A skilled master shouldn't fail simple tasks 5% of time nor a bumbling buffoon succeed at highly specialised and difficult tasks 5% of the time.
