You have an entire week to play your official. The following week you will have Good Friday (bank holiday in Ireland unsure about other countries), a normal Saturday holiday wise, Easter Sunday which is a holiday, and then a Monday bank holiday.
I understand that people will be using some of these holidays to do something other than playing Warband but I personally feel you still have more than enough time to play your official on one of the days of Easter Weekend.
wtf u going on a 4 day egg hunt with the easter bunny or something?
