So with the new Tie Advanced pilots Juno sticks out and depending on what we see for Scum with wave 8 I think we got a Faction strategic theme going on here.

Rebels is about synergy

Support and combinations to make ships more powerful than they would be alone.

S&V is about control

Denying tokens and blocking with lower PS as well as enhancing damage for control based attacks.

Imperials is all about position.

With plenty of positioning correcting pilots as well as its own positioning correcting ship (even if it got nerfed to reposition before everyone else's move.
