Just be honest and say it out loud you are preffering players that are recharging and spending ingots in the game. The rest is not important to you and there are more and more events for whales and less and less good events for F2P players that are saving up coupons for months to be able to get a good ninja. You are not fixing your horrible matching system, so why should people even invest money in this game? Start by fixing your unfair matching system and let the OP players fight among eachother in PvP events instead of them having Auto fights with players that have 2-3 times less power. And when that is fixed, I will consider buying and spending ingots in the game.
