Temporary vip wepons

No. It will be to easy for people to run around with temporary VIPs all year long. As an event, free VIP's are good, but putting them into the item shop as temporary isn't a good idea.
That means that cheaters can get and use VIP's without the downside of loosing a lot of invested money, if they get caught. It might work if they can only be used for 1-3 days and have a cool-down time of a month to be able to buy one of these temporary VIP's again.

We had one VIP as a MP-shop Item in EU, but with a large cool-down time.
