The Nether
Let me try this again in a more constructive way. This activity does not feel good to play. They said in the stream that basic regeneration was disabled. Right now no sources of healing are working and it makes the SEASONAL activity unenjoyable. Is this a bug or intended. Gameplay slows down to a halt when you're (quickly) at low health and have to disengage from combat to go find a health pot, which also seem very stingy. This needs tuning or bug fixes or both but once more people are able to play it I guarantee this feedback will get louder.
Edit: Also waypoints need improvement
