[2021] Ice storm and other aoe effects getting cancel by other players' aoe

Hello combat fans,
I wanted to introduce myself, I’m DaveNW and I lead the combat efforts on New World. Thanks for bringing this topic up.

There was no change made to the AoE stacking logic. This is working as intended and has been working this way since Closed Beta.

We do not want long duration AoE spells to stack on top of each other as this will cause massive scaling issues with damage and healing output in combat. Stacking multiple Sacred Ground spells would result in players being unkillable and conversely stacking multiple Ice Storms would immediately kill opposing players, neither experience is something we want to have happen. When AoE spells stack on top of each other, the AoE with the longest remaining duration will take priority, we like the idea of coordinating between team members to maximize the damage and healing output of these spells. The less overlapping you have of the spells, the higher your damage and healing output will be as a team.
