Weekly reset, new mission comes around, 2nd boss phase some ground areas become constant AoE Taken infections. Meanwhile same season in a Battleground the very same AoE Taken Infection doesn't work and won't damage players.... Such stuff is just confusing and causes unnecessary deaths in PvE. If you use AoE areas both visually and gameplay-wise, make them at least distinctive and consistent. Not in one mission a damaging area and in the other not. Quality Approval is a thing, you know?
