While I understand that Vack's attitude is questionable, I do not think there's any official word about the exact design function of a job.

While it's true that Yohsi-P himself mentionned something of the sort, it would be wise to be reminded that it was in interviews that predated even the LIVE letters, and patch 1.20. At that moment, the job system was still, and I emphasize it : "under development". Which, with due respects to another's opinion, means that it can change.

Therefore, while your opinion is phrased in a much better way, Noctis, it isn't anything more than speculation and conjecture at the moment, be it as well-thought as it is.

As for you Vack, you may not wish to rely on another class to be optimized, but it would be wise that you remember that this is a MMORPG, which stands for Massively MULTIPLAYER Online Role-Playing Game. You'll never be as powerful on your own as you are with people. Sure enough, a feature that I like so far with FFXIV is that while there are things that require party play to be done, quite a fair bit of it is also done solo. However, even the solo content gets much easier with people. As the game itself says when you get a full party, there is "Strength in Numbers".
