Have weekly challenges that give 30min 1.5x coupons.
Have like 5 challenges you can complete throughout the week and foreach you get a 30min 1.5x coupon (exp, drop OR 2x party quest, you get to choose).
Intotal you get 2.5hours of 1.5x per week.
In OSMS alot of 2x events happen while here in phoenix we can get some bonus coupons but only from GM events that almost never happen and if they happen you gotta be lucky its on a time you can join… you dont even get to pick drop or exp.
Having a consistent but limited way to gain coupons could help casual players wanting to play more.
The weekly challenges could be a few things. To keep it fun for everyone you should be allowed to pick between a few options.
Challenges could be:
Kill X amount of a monster
Jump quest challenge
Get X amount of dojo points
