Darth Bane Proving grounds

Hello,

I wanted to know what we think about Bane joining the proving grounds challenge. I wanted to know because I'm hoping  that he gets moved after December. I'm slowly getting him by buying shards in the conquest store but I still need 2 more months to finish getting him, I'm at 110 shards and I will have him by the end of December. But in general what do people think?
