You might recall one of the players mentioning last time how they were aiming for the time boosters and by doing so, got more time boosters in return than the quests took, resulting in players literally building more than 15 Bears on their max level without spending 1 diamond.
It is not the debt of the players that Innos developement crew is not able to simulate its events before going to beta. And at autumn zodiac you could have seen on first view which way it would go. I cannot imagine that these guys are so bad in maths that they cannot recognize this before. I mean, one player even forcasted this scenario in the feedback thread. It was described, that the thing with time boosts would be more efficiently than in mermaids. Do you really read all posts? At the latest after this post you would have to understand it.
It seems to be laziness.
The same laziness which gave us in three successive events the identical selection of chest. That it does not work to copy the same chest/prize system on a new quest system u should have learned in mermaids. But instead of reforming the chest/prize system you made the same fault in autumn zodiac again, ok, let's say the balancing was even worse.
Bad thing, that the last 2 events disbalanced the whole game extremely.
With better preparation by taking some more time to play it through on your own in an accelerated simulation for example you could have avoided this devasting developement for the game in whole.
In your eyes time is money, why test an event sufficiently?
But quality needs time. Great balancing needs time. If u are not ready to present us a good balanced event, do not expect from your players to pay for it.
The same with "Winter Magic 2019". The first disappointment was the title - a copy from "Winter Magic 2018", second disappointment is that it is another copy paste event, this time from FoE. Third disappointment is the Evolving Building - a copy from mermaids.
Well Inno, perhaps put more effort in the event preparation. Things like the missing balacing or the incorrect information in several quests make me feel that the last events did not even go beyond the alpha state. We do not need mass of half finished events.
