They should if they know what's good for them. These days mmos are based on single-player RPG titles, good contents but not enough lifespan. Old school MMOs had much less restrictions. PvP was pretty much a player created content, the possibilities out shines rewards/endgames. That's what I want to see again. I believe they are increasing more staff for stormblood, so we may see yet something of the old modes revived.
