It is the most controversial mechanic of the game and one that other Supercell games do not have. The cost of these offers implies an attempt to improve metrics even from the smallest payers. The biggest drawback of this mechanic is that it negatively affects such players. Those who could have paid a little more will now take advantage of it. Most likely, this teaches players to optimize their spending and believe that they can “save up” for the purchases they want, which has an adverse effect on payments from these players.
