For those complaining about the gatcha event because the 0 stam map only has a 1 min timer and some people can do 3 runs and some can only get 2 or even 1.... the answer is simple: Upgrade your net / PC. If you do not spend the money to get reliable and fast internet then you have no right to complain about what you can / cannot do on the internet.
I live in Australia, I will never get 3 runs from these maps because of loading times and Australian internet, even our fastest will not allow 3 runs from this an that is with a top of the line PC. However, these gatcha events are quite generous and it is very unlikely that you will need even HALF the required currency to complete the important parts. Bear in mind that 90% of the first 5 gatcha pages are NOT WORTH GETTING.
Therefore I am quite happy with the way these events are run and I actually prefer them to the 3* all the stages to get the girl max or the shops with prices that force you to play the event map 6/7 days a week just to clear it all.
