I wish people weren't so derisive towards the topic. Personally I agree. You shouldn't make an encounter that's toothless on release at minimum gear levels.

That isn't to say the mechanics should be overly difficult, but they should be punishing. I think that's one of the main reasons I liked Weeping City so much. The mechanics aren't hard. They REALLY REALLY aren't, but if you don't do them, they'll mess you up in a heartbeat. That's what we should aim for in casual content imo.
