I'm thinking why not just release a huge TIE Advanced for the Imperials? This would kill two birds with one stone. Basically the huge TIE Advanced would be invincible the first 4 rounds of combat, could carry 15x Advanced Proton Torps and could fire range 1-5. It could do the new banked K turn. The added feature would be the fact that it has a choice to roll up to 10 dice on its Primary attack.
Coolest part of all it could use a Kamikaze EPT and destroy itself and all other other ships at range 1-3.
