Depending on the cost of your flanker, as was said in the OP, he will often be a primary target. The key is giving them a bigger threat to shoot at. The flanker cannot be the biggest threat on the table, IE Soontir or a Phantom flanking for a TIE Swarm. Most often, not engaging the swarm would be folly. I like to fly XXZZ with Etahn flanking, Soontir or Whisper flanking for a Swarmlet, as I said above, and I really like to fly double HLC bounty Hunters with Backstabber flanking. All of these lists include a primary force that can tear through many targets if it is ignored.

I think this is where that flanking idea starts to hamstring you at the building stage.
See I guess I didn't get the memo:
Captain yorr 24
Whisper acd vi fcs gunner 44
Soontir ptl 30
This is the Nationals list. Technically both whisper and Soontir are flankers..... Nope.
I try and think of a term I'll call damage potential. Whisper and Soontir have high damage potential of they aren't shot at my a significant number of ships. That's a normal game.
Versus a falcon I'll try and push the lambda in more and whisper at r2 while Soontir stays at r3. This is the best possible damage potential. Soontir dies too easily with no hull. Whisper will last longer with an evade and buzz saw doing the bulk of the damage.
