Unless you are on that world first clear I do not see how this applies.

It may very well be that with these ilvls you can only clear certain content with certain classes, this has always been the mantra of the elite.

But I don't think this is the right crowd for it, for example. There is a difference between playing your class to the fullest and needing to switch classes in order to complete something.

If the majority of players feel that way it will most definitely be changed.
