1) That data you showed isn’t a ranking of the ship meta or which fleet beats which. It just how many of each fleet are in the #1 ranking in shards. Those are not the same thing.
2) I usually run x1, Fighter, Bomber in the starting lineup, and then Interceptor, Shuttle, Gauntlet, and Defender in reinforcements, who gets called first varies. Not sure if it’s the optimal lineup or not, I’m still playing with it, Interceptor is nice bc it reduces ALL cap ship cooldowns by 1 if x1 is present and it’s in reinforcements, however it does limit your fleet to ONLY Imperial/Sith/Inquisitorius. I haven’t tried using Defender w/o Interceptor yet. As I said, I can usually beat Negotiators consistently except when Han’s Millenium Falcon is in reinforcements - considering trying dropping Interceptor for HT and see if that helps with this. Malevolence near 100% win rate if you play it right. Same against Home One. Slapped the snot out of a 5* Executor the other day but lost to a 7*, I think it may be somewhat dependent on how the opening breach/mark goes down.
For reference my ships/pilots are:
7*x1 / r7 DV
7* Fighter / r5 TFP
7* Bomber
5* Interceptor / 6* g11 2S
5* Shuttle / r7 EP, r5 RG
7* Gauntlet / g7 GS, 6* g8 ISC
5* Defender / g11 IV
So as you can see, still quite far from optimal, yet quite potent nonetheless.
