5 health behind 3 agility, and a sweet dial with the best action bar in the game. Defender has a worse dial overall but has a white k turn, one more health and a better distribution of hull and shields with a worse action bar. Not worth the extra 5 points.
E wing has a worse dial, better distribution of hull and shields, worse action bar, and can take an astromech. Not worth the extra 2 points.
IMO both the defender and E wing should be 25 points base, perhaps defender 26 and E wing 24.
