Based on my observations of how players advance their characters as they level, the ASI seems to be more of an imperative to them, with perhaps some players opting to go early with split feats versus the full ASI. Once the players get their 20 in their primary stat, they’ll focus solely on full feats for the most part. That’s my take on what happens in game.I can't speak about an individuals "feelings;" however, I high stat is definitely not needed in 5e.
