We appreciate your suggestion and may consider it in future event. We want to emphasis that BB7/CV7 is the ultimate ship and it is supposed to be rare and hard to get so we have to set a limit of number. 

At the same time we believe free players are very important too, so we also provide ways for free players to achieve this goal. 

I get the limit, but what I'm trying to say is your kinda screwed if your 16th. I'm not saying the 16th should get a bb7, but after spending $500 and you are 16th you get nothing. It has little to do with the bb7 and everything to do with investing that much and getting nothing if you happen to be 16+
