I don't think it would be appropriate if the fight were any easier. My group wiped on it once, then we got through it the second try no problem (I was i213, for reference). The mechanics require attention but aren't unfairly difficult. Requiring attention is the main thing here - the content from the last patch (Void Ark in particular) was just way undertuned, to the point that it was faceroll from day 1, first try. Final Steps and Weeping City are both incredibly fun and suitably challenging instances, in my opinion.
