Wow. That's a nice mechanic. Very motivating
It’s dumb that are limited to 12 tickets when some things cost 10. We can save up hundreds of Undaunted keys. Why not tickets?
Is there an official reason why tickets are limited to 12? A quote from the devs? It’s easy to make up reasons.
Events are designed to spur game activity and keep the game busy. They want you to participate in every event. If you could stockpile tickets, people would just do the events they like and ignore the others. By limiting your tickets, and having event items only available for a limited time, people deplete their tickets quickly, and need to participate in current event if they want more. Also, by running you out of tickets quickly, it makes events friendly to casual players. At the most, you can be 12 tickets behind someone else. It is one thing to feel way behind veteran players for long-term, serious content like PvP and Trials. It is another to feel way behind veteran players for events which are supposed to be simple and fun.
