Kath & The Party Bus
Swap Engine and Mangler for GuidanceChip+HomingMissile
Target Lock will be your first and last action, then firing the Homing for a devastating volley.
You have 1 action in the game, before getting stressed forever....and I don't think a Boost for the first engage will be a nice choice. After the engagement, you will be full of stress, sk Engine Upgrade doesn't fit well into a partybus/bossk.
Mangler..the same. No Engine=No mobility=Extremely difficult to keep your target insight.
About Scarlet, doesn't glitterstim and PTL fight each other?
That's are my opinions. Nice squad, I'm a fan of Firespray+Bossk
