I agree. It wouldn't be a realistic way to get clears by any means, but at least you could get some real experience and practice with the fight in before tackling the content in party finder or with a static. There are many players out there like myself who are much better learners by experiencing content rather than just watching videos.
Hell even when they end up adding in DF access months later the clear rates are still terrible and most runs end up just being practice, so there is no reason to not make this change IMO.
