I do agree that the rewards are to hard to achiev.
Games like this are based on player willing to purchase some money to be able to save some "life-time". But atm even if you spent money to get e.g. more energy you will need houres of ingame time to achieve the rewards.
To me the only well balanced event so far is the „Hero upgrade event“. Most oft he other events are not worth it the try to reach the max points due tot he fact, that even if you have the ressources to do so, it takes way to much ingame time to get there within 3 days.
So an easy way to adjust some oft he events would be to raise the duration oft he event.
Ofc we all have to see rewards like this as an free bonus, but without achievable rewards, the motivation to keep on playing the game and spending a bit of money every once in a while will decrease significantly the longer you play.
I do agree that the game nets you with lots of rewards, but only at the beginning. After 5 Weeks all daily rewards are gone and most oft he challanges and missions are also completet. Thus the events become more and more important in terms of motivation to keep on playing.
Don’t get me wrong. I like the game a lot, but there ist still some adjustment to do. 😉
Keep up the good work!
