If the game is worth it I don't have a problem with monthly fees, but with Square Enix's track record I'm expecting this game will be slightly better than awful ...
With that said, many companies are so interested in MMO games because of their user fees. The reason for this is simple, after you have a large enough user-base you will break even and each user after that is mostly profit; and a very small dedicated user-base can generate more profit through user-fees than a larger user-base can generate through sales.
Hypothetically speaking, if you had a game like DQX selling 2 million units on the Wii/Wii U and having a userbase of 500,000 users who pay a monthly fee of $12 for 2 years you would end up with a game that was (potentially) as profitable as a game that sold 5 to 10 million copies.
