Can someone explain to me the worthlessness of Agility?

[Laugher]

I would not go as far as to say its worthless, but in terms of AC it does not calculate precisely the way it did on live here on EQEmu. (Frankly I have no idea how close/far away it is from accurate, but I know its a long equation that currently works as close as anyone's gotten to live) AC does factor in, and I'm sure agility will help increase that, but the exact value of increased protection caused as a result remains arguable.
