kvk winners diamond minds

Hello,

I have a question. Why does it take 7-8 hours to regenerate new diamond mines, Specially the lvl 5 when it already takes 5 hours + for them to start showing on the map?

also if this is the way it is with just a few lvl 5 mines, why do you even have the pricey, long research to gather more quickly from these minds. If I can do a lvl 5 mine in 3+ hours and someone who never researched the second section on gathering diamond mines take 5 hours, But new ones do not drop for 7 - 8 hours. Why even have those as a requirement to research as it is a waste of time and resources when it matters not on weather it takes 5 hours or 3 hours to harvest when the drop is every 7-8 hours.

The drops also ends about 1 hour before the event ends. so in actuality the winners get get lvl 5 mines for about 17 hours in total time or about 3 drops limited mines. then they ones on the map start to disappear. so it is only 24 hours for lvl 1 mines being dropped, 23 hours for lvl 2, 22 hours for lvl 3 19 hours for lvl 4

this is also for the losers having to wait just as long for the level 3 mines

i think it should be every 2 hours during the 16 hours they are on the map or even 3 not 8 hours

thank you

ps I love the game and learning about it every time I play
