There clearly is an issue with falcons being too prominent in lists you only have to look at top placement from tournaments, when you have a bunch of great ships you cant fly because superfalcon only has one decent imperial counter that needs looking at.
There are lots of decent Imperial counters:
- Kath + Rebel Captive
- Brath + Predator + HLC
- Jonus with wingmen carrying Cluster Missiles and/or Proton Torpedoes
- Standard swarm (Howlrunner + 6 TIEs)
- Interceptor swarm (Howlrunner + 4 TIEs + 2 Alpha Squadron Pilots)
- Bomber swarm with Seismic Charges
- Phantom + mini-swarm
