I'm glad you know exactly how it will work already, thanks for the insight. If they made it where the content can be cleared with iLVL55 gear then it shouldn't be too big of a problem. Fact is, this is how it will launch. You'll have to see how this plays out.
I am overgeared for it on multiple jobs but that doesn't mean I don't think other players should have a fair shake at clearing the content. I'm entirely confident this was their plan to set it up with 3 sets of 8 thru the Duty Finder so that geared players would actually try it out with people they do not know. Later on they will likely allow it to be set up as a 24 man pre-made but I'd be willing to bet they haven't got around to coding that yet.
