In one of the threads on here, snk mentioned a desire to replace the current event coin items for new ones, for the new year.
With easier ways to acquire event coins, such as Facebook uploads every now and then, VIP (hopefully not anymore, though), etc., I believe that new event coin items are needed. The current items being sold are worn out, and common now. Also, with the growth of the Player Relations Team, there are more events being hosted, allowing more event coins to be won. This also means a decrease in rarity of current items.
Frankly, my point is that the current Event Shop is a little dull, and could use a little more "pizzazz".
