We're aware of an issue with Moondragon mistakenly taking AoE/team damage that should be shunted instead to her teammates. This issue will be fixed in R280.
In the meantime, with tomorrow's data patch, we'll be making it so that she simply doesn't take AoE damage at all (unless her allies are down. In which case, it's not really AoE damage anyway). This does mean that outgoing AoE damage will be weaker than it should otherwise be, but we figure that's better than having her taking the damage in the first place.
IE: Now Moondragon, Spider-Gwen, and Wolverine take 1000 AoE damage. Each character takes 1000 damage. Total 3000 damage.Tomorrow evening (6/16) Moondragon, Spider-Gwen, and Wolverine take 1000 AoE damage. Spider-Gwen and Wolverine take 1000 damage each, Moondragon shrugs. Total 2000 damage.R280 Moondragon, Spider-Gwen, and Wolverine take 1000 AoE damage. Spider-Gwen and Wolverine take 1000 damage each, Moondragon hands her 1000 damage to either Spider-Gwen or Wolverine randomly. Total 3000 damage.
