In Epic I find the following decent:
Black Squadron TIEs with Snap Shot backed up with a TIE shuttle with at least Operations Specialist (prefably Jonus with also Snap Shot, Tactician, Lightweight Frame).
Many have already mentioned TIE Advanced. I'd go with Tempests with Accuracy Corrector, Cluster Missiles and Guidance Chips. Load them on a Gozanti with Requiem. Alternatively use Ion Pulse Missiles.
Looking for something different Gamma Squadron Veteran Bombers with Snap Shot, Unguided Missiles and Lightweight Frame. Played him last week with the Black Snaps a tough little guy.
I do not find Interceptors any good (but then I can't fly them for toffee anyway). They could do with a counter attack like Armada to justify themselves in Epic.
