Anyone worried about the idea that "75 Feats" will make Session Zero a slog - you don't go looking through 75 feats at Level 1. You pick a background and it gives you a feat. You can custom-make a background, but that's only if you WANT to add that level of complexity. Similarly, you can STILL take ASIs at Level 4, etc.
For those that don't like Feats, they're still essentially optional - your background feature is just feat-like now. (In that it's called "a feat" and actually does more than free room and board).
