Equipment farm events basically are the breaks. Shifting Lion's Treasure up, without bumping everything else up accordingly, was a bad call, or a bad series of calls. It wouldn't surprise me if the original intention was to shift everything up, but then they realized later that they wouldn't have the next event ready in time.
Or... here's a (highly unlikely) idea I'll throw out there: they move up Lion's Treasure, intending to give us the original 2 week version of Feisu/Face/Faith's event next. Then at the last minute, it gets changed to the 1 week revival version as they suddenly recall that rep grinds pissed us off. Lion's Treasure does not get extended, as we have a tendency to not get nice things.
