Interesting article criticizing "overwatch", it's artificiality and lack of player control. Interesting, as as of now, BG3 removed perfectly fine reactions system, in favour of automated, uncontrollable toggles. Perhaps, nicely implementing reactions would be a step forward, rather then backwards afterall.

Though that's not quite accurate, as "ready action" would be an equalent of "overwatch" though as I read 5e rules it is a bit more specific then that.
