The ability to rotate your Spartan's stance on the profile and keep it locked that way... Has that always been there or is that a recent addition? I almost can't believe that it could have been there this whole time and I never noticed until now, but if it added sometime from last summer until now, I somehow missed seeing it. I just now noticed though when looking at someone's stance and their Spartan was facing away. I thought 'Oh, is that a new stance that I never saw?' but then went into the req collection and looked and found the exact stance they had but not in the same orientation. So I went to the customization menu and selected the stances and then noticed that you could save a rotation. It's a nice addition but most of the ones I've unlocked don't particularly look 'better' in a different orientation than the default.
