FFXIV is not a hardcore MMO. It was designed with casual gamers in mind. Anima and Rest XP means that I can play the game seldom 1-2 hours a night, maybe less, and still enjoy it just as much as someone who doesn't have work/family/other responsibilities. I don't have 20-30 minutes to waste running on a Chocobo when I only have 2 hours to play, I wanna log on, look up a quest i've not done, go do it. Use anima to facilitate me quickly moving from a to b, have fun, log off.
