I read somewhere that if costs had risen so much, it was Apple's fault... Even if I don't really see what Apple has to do with the increase in costs when I play on a PC, I can hear it. It's just that I would necessarily spend less with the new prices.

However, I've noticed that while costs have gone up, dungeon rewards have gone down. Until recently when I used the double energy spend on a 50 battle multi, I would fill at least two dungeon loot cells. This is no longer the case. The same goes for getting my artifacts up, the expenditure was less. Now, for blue in 5 or 6 stars, I sometimes spend 2000 to 3000 k to get to lvl 12 of this artifact. What to say also about the 4 stars glyphs recovered in the wars of faction. E,n apart from the pre or the speed, those of attack, of HP or of Def never pass, it is just of the expenditure at 50k for nothing...

It's hard to do the Artifact challenge until the end.

Finally when I see the cost of stones to get champions, I smile softly. I'm not sure how many stones I spent to get 2 Golds and purple champions identical to the ones I already have. So far, I've done quite a bit to heat up the blue card to evolve in game, and I still don't pass level 15 of the spider... 

As a player for a few years, I knew the principles of spending more to earn more, but spending more to earn less, I didn't know.

And I'll be told that it's still Apple's fault... 

So it's probably time to go back to FP and lose interest in the challenges since even buying energy and multi-battles doesn't help you to complete other challenges.

Have others than me already noticed the difference since some time, about since the costs of the shop part have increased?
