The new Master Tier border is lacking a consistency that previously existed.

The current Master Tier border mimics the Challenger Tier border's assets. It has the extra little extensions at the bottom of the border.

The previous test border also mimic'd the challenger assets, as seen here (http://www.surrenderat20.net/2015/10/1021-pbe-update.html#more) [scroll down a bit].

The newest border (http://1.bp.blogspot.com/-QKtg3SSgTeo/VjhkoctEDeI/AAAAAAAAHys/wQCSbwTGKAU/s1600/brmc.jpg) does not have any of the extra features of the challenger border.

It'd be nice to see at least something extra added to the top/bottom of the border to separate it from the silver border. The current master border seems a bit under whelming.
