Thoughts On Couple Based Squads
Dom+Rainy (don't really need protection or heavy support but can't really defend a supporting character great while still watching out for each other either. They have a good mix of good melee and ranged, but aren't the best at either. They can take whoever is leftover.)
Charlie+Rabbit (could use the protection of a melee character. Charlie has pew pew pew cover and Rabbit can dish out damage with psychicness in limited supply, so a heavy gunner might be less useful than an ace melee fighter to watch their backs; like Rana or Helen. Rana preferred due to his auto-protect while wearing one of those masks).
Dex+Ready (could use the protection of a strongman like Rana especially, some less physically strong but awesome melee fighter like Helen next best, or ace gunner like Jinn/Giska/Snake third best)
Bea+Stig (add Giska, Snake, or Jinn to add more ranged to their melee awesomeness; or they're fully capable of protecting a supporter character like the Bioengineer or Stormy)
If we stick Rana protecting Rabbit and watching Charlie's back melee wise, that leaves either burly Jinn the gunner to lift Dex's wheelchair or awesome melee defender Helen to make sure Dex and Ready aren't eaten up close.
If we trust the people we know better, and plus we've had Helen defending people this whole time, to defend our favorite nerds, everything can start to fall into place.
Charlie, Rabbit, Rana
Dex, Ready, Helen
Bea, Stig, Stormy/or Bioengineer
Dom, Rainy, Giska
Snake and Jinn take either Stormy or the Bioengineer, whichever is left over.
