The real answer is of course, I will wait and see, but in the interest of playing along...
They are trying to address two problems I have, which are closely connected. The human race (not us, just the D&D one) and feats. I limit and don't love feats, and I know the default human is underpowered. If feats are fixed, and so far it looks promising, then a two feat human is fine!
That could be a couple of house rules I could take out. I have another on short rests...so curious to see what happens there.
On the other hand, if crits staid as in this playtest, then that is house rule number 1, but I think they will back off. And inspiration, not sure, just can't make the call yet.
