In Dragon Age: Inquisition we have these. The player gets to [censored] around with repetitive tasks whilst the game does its little countdown.

Personally, I don't mind them, but some of those in Dragon Age are just preposterous. No one should have to wait 24 sodding hours for something like that to complete. I don't think they should have stretched it beyond 3 hours.

Anyway, as per the title, what do you think about these missions?

That's a waste of time. Why add missions if there's a 'sit back and do nothing' option? May as well take the 'Wet' route and just be a movie game.
