Hello,
I had a awesome idea, maybe it's a nice thing for making a VIP function in game.
I also have some extra information how you can it into the game.
How can you become a VIP?
Add an option for pay 19,99 €/$ in the threasure section.
For that money you can become 1 month VIP
What you can get from this package?
-100 gems/day (=3000 - 3100/month)You get more then buying for 19,99 €/$ gems, but you need to wait 30/31 days, till you get them all.
Also when players really need them, they will pay again for normal packet of gems.
Its a win win situation for players & supercell.
-Collect all button
-10% faster elixir, dark elixir & gold boostSome more benefits for that money..
-30 mins free boost on barracks every dayEveryone can use this.. :P
-VIP StatueIt will also get deleted when you arent VIP anymore
-BadgeSpecial badge left off they name
-..
If i have more benefits, i will upload them into this topic. 
Hope you guys like my idea! 
Greetz,
