There should be a trading system in which you can trade in etc items from monsters for blue wish tickets.
For example,
- 100 cotton for 5 tickets
- 100 shark fin for 7 tickets
- 30 pianus sculptures for 20 tickets
(the harder to get the more tickets)
Why?
-Some people prefer to train rather than go to events, this way people who doesn't like events can also get blue wish tickets
-Economic system: some people don't like to find these items themselves so if they are rich, they can buy it from others.
-its hard for people to get 1bil that quickly and not everyone wins events and the it takes 20 tickets for 12 demon pots which is 20 bil for 12 pots only
