I'm not sure if this has been suggested before. I have always enjoyed tie swarms, and I think with the addition of Youngster the damage potential of the classic Howlrunner swarm can be maximized...
Here is what I am thinking:
18 pts Howlrunner
19 pts Youngster + Expose
14 pts Wampa (for chance at guranteed damage)
13 pts Obsidian Squad
36 pts Academy ties (x3)
That gives you a total of 7 ties with Howlrunner for rerolls and Youngster giving each tie 3 red dice. You could always trade out Wampa to upgrade 2 academy ties to obsidians as well.
While this looks fun on paper (21 red dice flying every turn and even more if ships get in range 1) you are losing 1 agility on all of your ties for that turn, and the ties are losing their actions in exchange for an extra red die.
Does the addition of a 3rd red die for each tie make up for the lack of focus and the loss of defense? Howlrunner is still in there for some dice modification at least.
