Only need one character?

[HEC]

It goes both ways:

- If you decide to have a single character and just switch classes / jobs you'd have "shared" pool of items (which is both benefit as well as issue as you'll soon start running out of space) and most of all you can "borrow" some actions and traits accross the classes / jobs once unlocked which is impossible if leveled on separate characters

- If you decide to level each class or at least group / disciple separately you'll benefit with less clutter in quests and items storage, possibility to "re-do" the quests (unless you find it boring) however you'll be unable to share traits / actions or even any of the items (directly) as you can't moogle mail your own characters and even if you'll use the middle man (some friend on the same server) to transfer the items you'll be unable to re-use any of the used gear as it will be already bound to the original character.
