Reason behind The Whorleater Extreme is not DF?

[Zaiken]

Is there a reason for making The Whorleater Extreme not in Duty Finder? Does it need a certain specific class role to Completed like Coil or something? How do they expect people to Learn the fight and what about people who are not in FC, or in FC that don't have enough people willing to do it with? Every Party Finder is Must Know Fight and Must Clear, Death will be replaced, etc. all the time!

Will there ever be Whorleaster Extreme in Duty Finder in the Future. Right now Party Finder is too much Elitist and so much Drama like death = replaced, must clear and know all fight, must clear before, etc. etc. Can we Please get a Duty Finder for this? It doesn't hurt anyone right? I want some good practice without all this inconvenience.
