I think a concept called 'Clash Loans' must be started so as to give players just the push they need to upgrade whatever they they want.. For loans of a specific value range, a specific time period must be given for returning the money along with interest(interest day wise) (the interest factor can be decided later)..
For Ex: Value (gold/elixir) Days
0-1,00,000 10
100000-750000 20
750000-1500000 40
The player can return as much money as he wants at any time and if he pays the whole amt back before time, interest will be charged only for the no. of days taken to return the money back.
Also they must keep the stock(defenses,gold mines or elixir collectors, walls, storages) of equal amount as a safeguard with bank.If a player fails to return the money on time, as a penalty the objects he has kept as guaranty must be demoted to required level or disappear to take the money back(how much an object should be demoted is determined from the amt required to upgrade it). Also the amount of loan the person is eligible is determined by the things he is keeping as guaranty..
If any more details are required please feel free to ask.. And i hope the management will certainly give a think to this
Thanks
