"PS: Once the Grocery Store opens, the Ranking, Survival and Arena Stores will be closed. If there are any items/ninjas in these stores that you want, please exchange them in time to avoid unnecessary losses."

So, if we dont spend ranking, survival and arena points we lose them? I understood that when the other servers upgraded to 5.0 their points got converted to equivalent points in the new shops. I was wondering if this message was only to inform the clients that certain items will no longer be available or if i should start spending what ive been saving for 5.0. Thanks.
