I'm not, actually. Because.... a. he's sure to be hell to gear b. he'll possibly be Rebel, Jedi, & Resistance. He might make any one of those teams the undefeatable, ever-present meta team and it's back to nearly everyone playing the same team and it all comes down to speed. He might make them all OP and then DS or hybrid teams currently viable suddenly obsolete. My (Sep16) shard right now has an interesting variety.

Of course if he is in all those groupings it might take awhile to figure out the team to build around him (esp if it didn't involve Chaze), or several options might be viable in a RPS way. If he shakes things up and makes them interesting, that's good (even if hard to gear). If everyone has to have him and some multi-Zeta-Jedi team is suddenly the only one worth having...meh...

It would be great if he had some strange synergy with only classic (orig trilogy, not Rogue One) rebels so that they (Leia, Ben, Raid Han, R2, etc) were a viable arena team instead of stepping-stones, raid-squad-only, or trophy characters.
