Essentially, everyone who had made it in the top 100 has not much more to strive for other than duplicate sets. Repeating the same gear for each season is not cool. It de-values the uniqueness of each season.

Now, those who had mostly pvped for the chance at the rare reward has no reason to pvp for titles/glamour anymore since they probably already have what they wanted, which might potentially remove hundreds of avid pvpers from the feast queue to instead play frontlines or other pvp modes.
