Nodes six and 12 are probably the most difficult nodes in my experience. Six usually isn’t much but sometimes I’ll draw a team with good synergy and it’s kinda tough. Don’t worry, GW is only difficult until level 85. After that, it gets easier and easier.
To complete GW, farm Phoenix, or Zinn lead Resistance, or Wedge lead Rebels, or EP lead Sith/Empire, or Nightsisters. The easiest one to farm is Phoenix.
Without at least one of those teams, you’ll need fifteen characters (three teams) with good attack synergy and quality healing.
It’s not supposed to be easy but, it is only a mid-game challenge.
