I've played a few now this week cause I missed J4Ws during it was the featured boss. While I was playing, I realise that there are alot of Guardians leaving Mid Deep Dive or at the start of the first encounter. NGL, it frustrates me so much. People know that this activity doesn't allow mid game joining right? I get it, that one Rando did not know how to "Invoke Darkness". Still kinda a -blam!- move to leave imo. Seperate the playlist for people who want to "Invoke Darkness", challenging themselves and people who just wanna chill and do some Deep Dives. Also please have a penalty for people leaving Mid game. Just like Gambit. Especially when the playlist doesn't allow mid game joining. That's all.
