That part caught my attention when it was first posted, because I couldn't figure out when "the past" was referring to.

He mentioned that MND was not being adjusted but then said it had more of an effect than in the past, implying there was a time when MND had even less of an effect on Cures than it has at this very moment. I assume it is either a reference to an extremely old update that I can not even remember, or the vaguest and most unclear reference ever to Cure V becoming much more prevalent as players have gone from 75 to 99.

There was a big update to the Cure line back in 2003, but the update notes don't mention MND. Maybe it was later than that if it existed at all? I no longer expect what the Community Bros say or what the Development Bros do to make sense, so I didn't look too hard.
