Well of Radiance is no longer turning your fireteams weapon damage into super damage but only does it for the player casting the Well. This has two major implications:
- Focusing Lens does no longer buff any weapon damage of fireteam members standing in a Well of Radiance.
- Fireteam members can no longer shoot through shields when standing in a Well of Radiance.
The game does recognise the Well's 'owner', therefore other Warlocks running Well of Radiance still dont get the benefits when standing in someone else's Well of Radiance.
