Although I was disappointed with some of my purchases in this game, I can’t agree with you.
First of all, false expectations lead to disappointments. So, think and read before you buy. Yes, it is a common place to complain about 10x draws for gems. Just be aware about it.
Secondly, VIP access with a second builder is a very nice feature to use, as well as flash offers with rare ascension items. Not all of them, but you can choose.
In addition to that you play this game for free, but developers work full time supporting and improving the game you enjoy. So, consider this a donation to express your attitude to the game and ability to say “Thank you” to developers and “keep up good work”.
