Before rogue bombers you could just ignore squadrons with 3 assault frigates and focus on killing ships. Might as well get used to it now though because we're almost to the arrival of Wave 2.
Ackbar may be enough to tilt the scales where you may get away with 3-4 frigates and minimal satellite squadrons. I havn't faced him yet and he honestly scares the bahjesus out of me.
Ackbar is broken IMHO, you should be scared of him.
The one thing with wave 2 is there are a lot of ships with 2 anti-squadron dice. Hell Glad IIs have them now on the Imperial side. I will probably play with some squadrons but I am not that worried about them. I have been a big advocate of squadrons from day one mainly because I love playing them. They have been and will still be a gambit in just about any build. The 5-6 rogue bomber squadrons are what you need to be afraid of but you wont see that too often since that means people need to buy 5-6 squadron packs.
Ackbar not broken. I have him where it was shot out only the side and give up two red and a blue for two red extra on the side shot. Unless you run a mc80 right between two ship. Or place the fighter on his nose. And he cant shoot them
