Is there a list of known formulas for int->crit rates for the different classes at level 70? From what I understand, it's a y=mx+b formula. When I need to figure it out I just throw in the values from 3-5 of my friends into my calculator and let it figure it out, but that's a pretty rough way of doing it, especially since my data is skewed from character sheet rounding.

Are any of them known?

You only need the y=mx+b for figuring out how much int = 1% crit at different levels. Once you are 70 it is a constant.

That thread lists it as straight X int = Y crit, and everything I've heard says that's not true, but that it's a y=mx+b formula.

EDIT: Nevermind then, I fail, let the thread die please >.>
EDIT2: Hold on a sec, if 80int = 1% crit at 70 for my priest, why am I getting 4.6% base crit instead of the 5.84% that armory's showing? Unless base crit =! crit from intellect, in which case I need those numbers as well.

That thread is indeed inaccurate. Stat conversions are indeed a y=mx+b type linear conversion with a non-zero intercept value. Most people simply ignore the intercept value though since it doesn't affect the marginal effectiveness of a stat, only the total effectiveness. The conversion thread only lists the marginal effectiveness of a stat, it doesn't list the base bonuses of each stat, so the totals calculated from just those rates will not match your actual totals, you must also take the intercept into account.

Assuming the 80 int per 1% crit conversion rate for priests is accurate, and based on your actual base crit from int, then it would appear the conversion equation for priests is:

%crit = 1.24 + int/80
