Why do you create an event where it is impossible to complete all the milestone without using any refill?
There are 125 stages total. That requires 1,875minutes total. If we agree to remove the first 8 energy that we start with, it still requires 1,755 minutes which represent just a little over 24hrs.
Since the tournament duration is exactly 24hrs, we are force to use/buy a refill to get the final milestone.
How can you guys ignore this? At least give all the player a free refill.
This is the kind of stuff (minor this one) that is getting your player frustrated.
