Well FWIW I bought and opened a few Grand Chance Cubes since for Xmas I had a lot of CC sitting around. I realize I can get credits by selling the cubes but I was curious to see what I can get.
Pocket Sarlacc
Flamehair Kawakian Monkey Bird
Hinterland Whitefang
Overloaded Peacemaker Armor Set
Pet Skarkla
C2N2 Target Dummy customization
Emergency Medical Table
Chair Emote 9
Pale Blue/ Pale Pink Dye
I am a casual player but I was happy with what I started out with then it seemed to tail off.
