Since Flare doesn’t allow us to “choose” the ninja event tier ourselves, at least allow us to “clock in”. Once the “countdown timer” for ninja event appears, a button to “clock in” should appear as well. When a player clicks the button, then he will be able to play the respective tier according to the trophy when he pressed the button, not when the event starts.
The reason is simple, offense is indubitably overpowered now. Everyone scrambles for trophy last minute. It is doable for some who are awake or free 1 or 2 hours before the event starts, but what about those who live in a timezone where the events starts at 3 or 4 am or during office hours? If a player is able to reach 5300 trophy 2 days before Ninja Event, he has already proven himself worthy of the tier. He should be able to “clock in” and not scramble with the rest of the world at a specific time.
p.s. alternatively, allow a “participate” button like pro league. The tier depends on the trophy at the time the player clicks “participate” even though the event has started.
