FFXI (and most likely XIV) are different in that XI has jobs and you could play every job on one character. XIV will also have jobs (different than XI, but it sounds similar to some degree). The devs never imagined people having 3, 4, 5+ jobs @ 75 thus needing so much equipment. They've learned a lot since then and I believe they'll implement that in the game. With that said, if they keep the same design mechanic of doing everything on ONE character, then yes, they will charge more for extra characters. While annoying, I don't have a problem with this as long as they alleviate storage problems that XI had.
