I wish megaservers became the norm. It's an MMORPG, a social game, so it's more than understandable people wish to congregate in active servers - you meet more people, you interact more, you have more opportunities, it's livelier overall and feels more like a world.

It's a pipe dream for XIV at this point however. Guild Wars 2 has a nice compromise via server guesting but here it'd cut into their server transfer profits.
