I like the effort put into this post. It really shows how much you want this issue to be addressed and fixed for the better. Very in depth and helpful to the community. I especially liked the part where you said "thanks". That part really spoke to me. Very nice and well thought out post. 10/10
Why not have it last until the end of the anniversary event? You have the same amount of coupons, people won't be trying to farm 8 hours per day and hog all the maps. People who had plans suddenly found themselves limited to finishing all the coupons within the 9-10 days. You can even settle the rage of people being stuck and lost time to use their coupons. The only downside I can foresee is that people will be using all the coupons they have on all their chars...
Please make a new thread once you have figured out the reasons why it is dumb and are willing to explain your reasons why.
