I have been saving up to buy the 3 key/coffer legendary set.  I am nearly there and getting excited to do so.  I only like to spend a little money on this game and that only on items that do not get destroyed.  When I buy this set I will start saving for the rare set.  The  question is this...is the rare set going to be random pieces or will Plarium do the right thing and not give me a blue piece that I received in the legendary set?

Thanks,
