Not that it's had time to sink in, but we saw in the top 16 (all flown by excellent players, obviously):
4-ship Rebels
4 TLT Ys
3-ship Rebels
Brobots
Trip-Stress-Ks
Palp and Aces
Corran/Dash
TIE swarm
Whisper Miniswarm
Corran +2 TLT Ys
Miranda/Corran
Whisper/Chiraneau
Can we pull any information out of lists so diverse about what kind of list it takes to compete? I don't know, but there are some trends that I see. Please comment if you disagree, this is sort of an analysis at first blush.
Endurance: There was a lot of beef in these squads. All of them had either 1.) A lot of hit points, 2.) Regeneration, or 3.) high AGI + Autothrusters and/or something else to avoid damage. Usually there was some combination of the two. This may well be due to the necessity of bad dice mitigation over the course of so many games (and something to save your butt when you guess maneuvers wrong). These are not squads with slim margins of error. I don't think any of these squads were banking too hard on always being able to arc-dodge their opponents.
Brute Force: These squads generated a lot of shots, either through multiple TLTs and or many ship hulls. The exceptions to this was Whisper/Chiraneau and the Brobots list, which both only generated 2 shots, but both really hit like bricks and included extra attacks in case the first failed.
Variety: Looking at the Arc Dodger/Turret/Jouster classifications, I think almost all of these lists were hybrids. Nobody went all in on Arc Dodgers, Turrets, or Jousters. Almost all of these lists could shift strategy based on they list they were facing because no list had only one tool in its box.
What does this tell us?
I don't know if it tells us anything. I might have just wasted your time. To actually find similarities in these lists, I had to expand the categories so broadly as to almost make them useless. I guess if there's a real takeaway, it would be that you want a list that is decently tough to survive bad dice, but has a few points dedicated to jacking with arc-dodgers so you can make your guns count. There's clearly no dominant list now, so go to town.
