I think the imperials are missing a good general purpose ship in the 20-27 point range, like the rebel x and b wings. The Advanced was meant to fill this role, but 2 attack dice are near useless on anything over 16 points, in my experience. Hopefully the AutoThrusters can help the lower PS interceptors fill that role, or the promised "Tie Advanced love"
Personally this is where id love to see the tie scout come in.
I love that odd looking thing
