Funny story about vouchers i got one and it expired, i would rather have gotten 1 seal fragment as its far more useful. I fail to see why vouchers have a 24hr life span rather than the same as the event which would be a step in the right direction imo. Event quality has been going down the drain recently making me doubt that they care about feedbacks anymore a good example is the fishing event. Personally i will play even with * events but cant say the same for alot of your player base, i have seen what happens when devs start to get daring(e.g a naruto game changing characters looks) hope thats not us.
Merry Christmas
