Your concern is not really necessary OP. The FFXI people will not adopt the system anyhow. SE can add it (Is adding it) for the casual players coming from that BIG, terrible, worthless game. They will make the content too hard to do with random people. This is what I am hoping and therefore I will not doubt that. Plus, a huge part of FF is NMs at least imo. As long as it's balanced it should be fine.
