I think they should just send a free Tales of Adventure to every alt after being caught up to the most recent expansion on one character. That way, if you don't want to do NG+ for whatever reason, you still have the option of replaying the game normally just by ignoring the book.
I'd also really like a bank for all of my characters without having to get them all in the same server and FC with FC chest permission.
And in case it hasn't been said, I doubt it has anything to do with RMT. Just look at the current best sellers list. They will probably never make the game more alt friendly just because story and job skips rake in so much cash. I'm sure it would cause fantasia sales to dip too.
