The rear arc seems to be everyone's main concern besides mag-pulse warheads, advanced systems and the crew slot. I really wanna know how FFG is going to print it on the base. Looks like there's not enough room. Redesigning without making it look too different seems like a huge task. Maybe a new token/template for small based ships that allow a clear way to detetmine special rear arcs?
I find it quite easy to flip/turn the base 180° to do it (I have some homemade rules for the TIE/sf) but some folks might find that akward.
Just imagine: the rear gun can selectively (or one way) pass through the special white wings of the TIE... giving it a 360 degree arc. We just haven't seen it in the movie yet- deleted footage.
