I actually agree with an event rewards item that gives +30 to all stats and contains one slot. People will be vulnerable to the freeze status, unless they've voted enough for the scarf. The maximum amount of headgear slots they'll be able to have is 3, which means they'll be vulnerable to either stone curse, hidden players, or by the inability to spam, depending on what headgear cards they decide to place on their headgear. It will bring some versatility, while not being completely overpowered to PvP, and drain the economy of it's huge amount of Event Coupons.
If you disagree with the above suggestion, that's fine, but adding new items that are useful to our veterans, at a high cost, will increase the demand of event coupons, making our events more widely attended and increasing their value in our economy. Our event coupons need a boost in their usefulness within the veteran community IMO, though our items that we contain right now are great, lets add more diversity!
