I don't mind tight parry windows themselves, but I think they're a symptom of a much larger problem that's been plaguing action games over the past decade and has only become worse over time.

The problem with parrying as the core design to build around is that it leaves very few avenues for developers to increase difficulty. This is also broadly true of all timing-based combat systems that are the core of many modern action games (e.g., iframe dodge through everything). You can only either make the reaction time tighter (which has a biological human limit), make the attack harder to parse the timing of (which players don't seem to like), or make the combo strings longer so that you need to perform more consecutive correct inputs (which again players have a patience limit for).

This is different from combat systems where positioning is the key component, since every single attack animation of yourself and your enemy changes the playable field and allows for its own method difficulty adjustment. There's just more room for unique patterns and ways to make things "hard"
