Is it 100% confirmed that C6 gorou >> Non C6 illuga!!

Was pulling linnea got even her C1 early still C2 illuga

So is my C6 gorou better here in Zibai Columbina Linnea team ?

Also Gorou runs instructor or Silken ......

(If gorou runs instructor any of support gets silken and if gorou runs silken both sub dps runs aubade )
