I would just like to point out something to you.
We play this game. We play this game a lot. We know pretty much everything about how it works, and how that applies to us as players. We created the Final Fantasy XI wiki, which is now bursting with information on any given topic regarding this game. We even did some stupid things, like creating third-party programs to get infinite lines in each individual macro, take parsing measurements to see who did what damage when, how much of it, whether it was physical or magical, etc., but this was done so that we could understand the game as well as you developers do. Maybe we know the game even better than you do. We certainly understand what each job in the game is capable of, why that is, and how to improve the ones that are too weak, while balancing the ones that are just cheap as hell.
In short, this is what I am pointing out.
We know this game. We thus know directly how to fix it. You should trust our judgment.
Thanks for reading.
