I'll be blunt here...I'm not a fan of timed attacks at all. It can be tolerable for rare, super-powerful attacks, but if I have to do it for every attack and/or every time my characters are attacked, it's going to get really old really fast. Back in the days of Flash games, I enjoyed an RPG series called Mardek because of its clever story, character development, and writing. However, I really hated the battles because nearly everything was a timed attack or timed defend. Despite liking the series, I never finished it because that one element was so undesirable. If I was browsing steam for rpgmaker games and I saw "timed attack system" featured, I'd probably skip the game unless it looked amazing in a lot of other ways. And even then, I'd hope it was an MV game so I could kinda...go into the scripts and cut that part out.
