Who should phasma replace?

Pogba

I'm level 56 and just got phasma to 4*
Currently running

5* sid
5* lumi
5* chewy
4* Ima gun di
4* Luke

Still farming Luke because I think he'll come good when 5*
Also potentially will use fives when I get him to 4*
Was thinking chewy because I hear he becomes less useful end game, but he still has his moments. Ima gun di is decent too, does good damage and doesn't go down easy.

Chewie and ima gun di need to change
Useless cuz speed and not useful
Then my hi-ranked composition

Ima gun is really only good for his leader ability. If he is not lead AND your team is not all Jedi, then he should be replaced asap.
