Lain texted me today about practicing for this. So I guess there's a decent chance he'll go. Obviously not higher than 50-50, but yeah.
Zinoto, Lain, Roller, Gio, Tech, LOE1
Would probably be my pick for the 6.
With WTP or Leaf being added if one of them doesn't go. WTP WOULD be in regardless based off skill, but he is notoriously bad in crew battles. And Leaf is ~LOE1 level and a pika is a good asset to have in a crew battle.
KY should probably be something along the lines of..
Judo, Kero, Mr. Eric, Ralph, Shadow Phoenix, Kass
Soldier2 or Forwardair as alts encase someone doesn't show.
