I am a big fan and played JW:A a long time. I bought all of the boosts when I could because I believe you try to always make things right. I have always been VIP. Some people wrote here that maybe you do not understand why having a boost reset is important. Maybe you do not understand the money part of the problem from the player point of view. This is my Dracoceratops:
You can see I put 27 boosts on it. Here are the numbers:
27 levels = 2,700 boosts (1 level per 100 boosts)
2,700 boosts = 54,000 hard cash (100 boosts per 2,000 hard cash)
54,000 hard cash = USD $360 (15,000 hard cash per USD $100)
My Dracoceratops cost me USD $360 to get to where it is. I bought these because I see you rolled back boosts before when you knew the system needed change, and I believe you respond well to feedback. I still have boosts unused, and plan on still buying them in. With the update change, Dracoceratops will not be useful enough to battle.
If you do not roll back, my choice is to remove all boosts and put them into something else, which will cost me USD $180 because I will only get 1,350 boosts back.
I am requesting a rollback of boosts. If this happen I will be happy and continue to buy in the game.
If there is no boost reset, you still have a gain from me of USD $180 because I will roll back, but it will be the last income from me.
