You know, if you really don't care at all for the emblem, I would not bother either. But that being said, getting one chest is such a minor inconvenience, that, at least in my opinion, it outweighs the possibility of people regretting not having done it later, BY FAR. You could just look online and then get the one that you are missing. I don't think it will take longer than 15 minutes. Even if you don't know which one you are missing, it should not take you 30 minutes in total. But again, if you are absolutely certain you don't care, I will not argue. Just saying that it would be too bad to miss out on something just because of one chest.
