I keep reading these and shaking my head.
Another game I play did something similar. We all bought gems to gain certain objects. Then they changed the output of those items. Lots of complaints on facebook....and then they turned around and gave us amazing daily bonuses for a while until they were able to do a major update. It was close to two months.
And, to top it off, they "rewarded" us with a gem confirmation button. No more accidental purchases.
I'm holding out that S8 steps up, does the ethical thing and returns the alicorns to the original glory, but after the silence of the wedding alicorn I doubt they have a moral button in their body.
I'm overly frustrated over every game needing constant play even during sleeping hours to get a goal at this point. They are taking the fun of of it and destroying the games.
