So I've played the game nearly since NA release, and I've found it mildly disturbing that many items in the game have various abilities listed a certain way on a single item, but then written different on another. An example would be Fast Cast:

Orvail Pants +1 says: Enhances "Fast Cast" effect, while...
Orunmila's Torque says "Fast Cast" effect +5, while...
Lengo Pants says "Fast cast" +5%.

Players who have been around the game for a while have managed to deduce that they all mean the same thing; yet reading these, it can raise the question of "do they all do something slightly different?"

I have to assume that this just means that different teams of developers were in work on different items, and they all had their own way of writing item stats out. My curiousity is such that I wonder if FFXI will ever see uniformity.
