I'm about to tackle the last mission (no mods), and I've got a question before I jump in and kill myself. What should my team layout be? I have the Valkyrie, with 10 troops and a Hyperion tank. Currently I have 2 snipers, 1 shield, 1 heavy, 2 riflemen, and 4 assault. I have all the tech (and equipped with MAG weapons and Sentinel/Predator armor). I'm wondering if I should change up some roles.
