This content is meant to be a stepping stone in difficulty. You can't just jump straight to Chaotic as a casual 'who doesn't even do Extreme' and expect for you or anyone else in the raid to have a good time. You are doing yourself and everyone else a disservice.

Casual > Extreme > Chaotic > Savage > Ultimate.

People should already have to have cleared the previous step in difficulty to do this piece of content. Which would be Extreme clears.

Again. Gatekeeping sucks, but 'some' amount of gatekeeping is not bad either.
