Imperial probe droid obtaining shard requirements

I used:
5* veers G9 no zeta
6* snow G8
7* storm G12 no zeta
7* death G12 with zeta, but it's useless
5* starck G7

All of them around +70 speed, except starck. And I got smashed..... :D :D . Ok i didn't wait for filling platoons, and I sometimes forget to use the scpecial ability, but still it seems kinda difficult to me.

So I would suggest getting them all to G12 to be on a safe side.
