If gree are going to have overlapping events, then how about structuring it such that they contribute to each other? Folder drops for ltq's are a good example, feeds into raid bosses. A great example used to be the pvp and FvF events - participating in pvp contributed to FvF and vice-versa. Where there's a positive feedback of results from one overlapping event to feed into another it makes for great game play. Just overlapping events with no link is plain annoying.
