I don't like timed hits for player attacks because they're too easy to pull off and they just eat up time. Even if it's only one or two seconds per character, that adds up over time and makes battles feel like a slog. In Super Mario RPG it sucks.
However! In that very same game, there is a timed command for defense, and to me that's fun because then the enemy's attack taking a moment and eating up a little time makes sense, it's trying to throw you off or get you ready to block. And in Super Mario RPG defending halves damage, but if you block within like three frames or so, you take NO damage. It's cool as fuck and always makes me feel like I'm the shit when I pull it off.
So my recommendation to you is that if you're doing an RPG, please allow for that because I think it'll add replay value for people doing speedruns or low level runs. For certain attacks like magic though, those can be unblockable.
