Take a look at this picture. Some counters are sane and some counters are ill- posed in my opinion!
I am on-line now but there are timers off that force me to return later! The first two are such a kind. And the third is their brother.
Give less, give often.
Also for missions or Titans. Unless is a world-wide counter (expiring time) there is no reason to make people wait for. Done one, another one ready. Resources scarsity make people planning their game. People who play every day at the same hour of the day might find everything ready (kids and employees) but those play at random time and at random times they should stop?
