I just want to put out the reminder each turn in combat is, what.. a handful of seconds? And it's the same amount of time whether it's a turn with two characters taking action or twenty-five.
So, while one character may be fast enough to act before another character within that brief slice of time, that doesn't mean they're so fast that they can choose precisely when they want to act down to the fraction of a second. These are not superheroes like the Flash who see everyone moving in slow motion. And so it's reasonable to suggest that just the act of intentionally delaying your action can cause crucial moments to slip by that you lose the ability to interrupt. Again, these turns represent seconds, not minutes or hours.
Blackguards has a delay option and using it shifts that character to the end of the list. It allows for some meaningful tactical choices without being overpowered. Point is, the current setup is far from useless, and probably more realistic (and easier to balance) than the alternative.
