Ally/Neutral priority
For Ally formation: Andrea, Sophia, Shane, and Glenn is a must, other one can be Morgan, or Siddiq. You should build Andrea very well since she is a beast. Sophia good for support Andrea, so she can keep doing her ultimate to all enemies. Henry is good, but with Andrea, Sophia and Glenn in back row, Henry will always be at the bench. For Andrea, it will be better if you put her in center back row to maximize the damage.
For Neutral formation: Don't have enough tanker or warrior option in Neutral, so Abraham can put in front row with R, meanwhile in back row you may put Kate, Magna and Denise. If you have Gideon, put him in front with R, and you may replace Magna, and put Abraham in center back row accompanied by Kate (her role will be like Andrea in Ally formation but you can put her anywhere) and Denise to make all team got best healing.
