I have no problem with the new way of assigning coins, But I do find many of the quests are unachievable within 24 hrs. It takes most of a day to complete Valiant Little Tailor, even if you have your army ready. Similarly, to produce 1000 intermediate paper will require a Level 5 mill and a 3xbuff...and even then if you start in the morning you will likely miss it. Challenging Quests yes, but they must be achievable.
Perhaps a day's notice such as you get with a 'waiting quest' might help ad allow players to prepare.
