It appears like BW has quietly changed quite a few skins. My favourite blaster rifle the X-12 Riot Carbine (black/white) has now been given the X-12 Nova skin (white/red). Not impressed in the slightest.
I am guessing those skins are now going to be used for the cartel market
Soon every blaster rifle that is popular will lose that skin and have it replaced with a different one. That way they know their new cartel market blaster rifle will sell quite well.
