So I've been working through some Epic-based Imperial squads. Our local meta seems to gravitate towards 300 pt. epic matches, and a tendency to play rebels. Given that so many points will be spent on the CR90 and/or GR75 rigged for electronic warfare, then rebel escorts (no matter how good they are) are a distraction because the center of gravity on the rebel force will be the huge ships. So the most optimal Imperial strategy is to kill the huge ships: quickly, violently and without distraction. That includes the design of your squad. There should be one element 100% dedicated to fulfilling this crucial mission. All other remaining selections for the squad are tertiary to the objective to killing the huge ships.
So I've devised squad and strategy for your comment:
Torpedo Squadron 8
x4 scimitars (advanced proton torps)
Jendon + weapons engineer + ST321
Marek with cluster missiles
151 points
This leaves 149 points for escorts and flankers. One group of free ranging fighters would begin to tangle with the rebel starfighter escorts. Meanwhile, Jendon and the scimitars are flying slow enough to be dealt their target locks by Jendon before making their torpedo runs. Once the locks are dealt, the scimitars can break into two sections of two bombers each. One section would be escorted by Jendon, the other section escorted by another set of TIE academy's who can act as blockers. Marek is available to escort either section.
Each section, if they arrive on their designated target sections (a GR75, a CR90 bow or CR90 aft), should be able to cripple or destroy their designated targets provided the APT's hit with focus and lock. Once they have released their torpedoes and struck their targets, Marek is available to deal out precision damage with laser fire or cluster missiles.
As the bombers make their run, the free ranging fighters need to disrupt, distract and impede the rebel starfighters from attacking the bombers. That seems to imply plenty of TIE fighters. With 149 points for escorts and flankers, you can field a crap load of them. And you should. A lot of free rangers will keep the rebels away from your bombers. And you'll have points enough for a strong flanker or two to really disrupt the rebel defenses and chase down any rebel that attempts to attack the bomber sections. Until the bombers complete their missions, TIE fighters should not even concentrate on killing individual rebel pilots.
If you are looking at a CR90 and a GR75, I would potentially deal one section to the transport, and the other to the aft CR90. Once the CR90 cannot produce energy, the bow is as good as dead. And once their ordinance is gone, the scimitars can stick around and pick off the hulks.
