I find it pretty hard to believe SE makes these fights and then goes "oh well we have no idea how this fight is supposed to be won, but we're sure someone will figure it out." They design the fights very carefully to be won using a specific strategy and gear levels that is usually flexible enough that different people tend to come up with different ways of getting things done, but the end result is still that the fundamental things to win the fight that need done...need done. What, you think they pull those required ilevels out their arse? They know, far better than most players do, what it takes to win the fights they create.

And if only a handful would use this (which I also find pretty hard to believe)...incentivize it, like they do with everything else they put effort into that they want people to use. Achievements, vanity, whatever. Hell, make it mandatory to do the trial mode before you can even DF the group mode so anyone that is in a random group can be assumed to have some understanding of the fight. It's not hard and it would make endgame actually playable and enjoyable to a huge number of people that just plain stay away from "the hard stuff" because banging your face against a wall with other people and failing, and causing them to fail, ain't fun for most people.
