Seems to me like we'll probably have a list that counters it soon. The biggest thing is to work on reducing the massive ordnance damage either through mitigation or denial. Some things I can see..
1) Wes removes the focus token preventing them from firing.
2) Stressbots prevent them from getting the action they need to use to fire -- and makes them more predictable in movement when they need to clear stress
3) Biggs can use R4-D6 to absorb a ton of damage, so long as they aren't critting a ton
4) Arc dodging is still viable
5) Reinforced deflectors can reduce the burst damage
What else is worth doing?
These are good points, but just wanted to make some counter points for discussion purposes.
1) Wes removes one of the Scouts focus. And, in the case he becomes very popular and proves effective, RecSpec is a good option as crew.
2)Stressbot is not especially effective in my opinion. He gets the double stress on one of the targets if he lives, and in a lot of cases, as long as they get their initial alpha strike off, the Scouts wont care much about the stress afterwards.
3) Proton torps are probably the most popular torp right now, and it gets a crit in there to turn off R4-D6 (if I understand R4-D6 correctly. I admittedly haven't seen it trigger ever). I do think Biggs is a good option just by pulling shots his way though. I'm especially interested in these Kanan builds.
4) Arc dodging is much harder when you are trying to dodge 3 large base arcs with a very maneuverable dial.
5) Deflectors is actually something I've been thinking about. There might be something there.
I feel ilke I've posted this one too many times, but here's how I would combine my list
Send your squadron into the joust. Wes removes the token from the proton torp carrier. Biggs is going to draw fire from 2 torpedoes -- any crits he can pass to Wes. if he takes some big nasty ones, he can jettison the astromech to discard it. The stressbot will not be attacked opening round and can double stress a different target from Wes. Then try to use your Z-95 as a blocker in later rounds. You can survive the joust, and hopefully take it down. The only problem is I don't know if this list would fight *any* other list well at all.
