Certainly Sherman Weekend

Major_Rampage:   There is a limit to how often we can run the 50% discounts.  With the addition of 25% discount,  we can now discount things such are crew training or garage slots more often.  Also comparing this weekend's event vs another server's doesn't take into consideration that  many of the rules and limits we have based on the month or quarterly planning.  If you want a full picture to look at what each server is doing over the course of a month.    With our  Daily Missions (Advancing down the Line Parts I,II and III.) You can earn 175k Credits per day (on top of your normal earnings).  Check Point Missions giving you premium time,  and Operation Tanks letting you earn the Tetrarch, which you can't normally buy in game.   Our On Track Missions (that you can complete the Daily Missions while working on), that let you earn  consumables (premium and standard), equipment, as well as a premium tank (T-25).   I am sorry you are not happy with the current weekend event,  but I think when you look at the whole picture,  we have pretty awesome things going on right  now for the NA Server.  

Major_Rampage:   Premium Tanks are not involved  in the bonuses for weekend events.  However I do like the suggestion of involving the Beta Sherman,  It's too late to change this event,  but in the future if there is a premium tank related to a weekend event I will see what I can do to work it into one of the missions,  such as the Platoon Mission.
