That's not how it works.
If Sheydos is more capable of playing kj than starxo is, and starxo's skye is good then it's better to put sheydos on it.
Than have starxo on an agent he's beyond uncomfortable on and NOT his playstyle at all and incapable of adapting like sheydos is.
It's not black and white.
I'm done with this convo though, these things are obvious (or should be) so this convo is pretty low level.
