Happy Hour Double EXP Event - Double Auto Attack cost (From 10k/5 mins to 20k/5 mins)

7pm-9pm Monday to Friday X2 EXP

or

Saturday-Sunday X2 EXP

Every hour, have an automated annoucement how many hours left for X2.

Basically the implementation of this event brings in two things:

1. New players would be able to catch up and not feel bored of the constant grind.
2. Players would be more open to creating EXP parties and interacting with each other rather than opening up fights with each other.
