2.2 Arena point formulas

Cyn · 09/25/07, 9:40 PM

Blizzard now have an arena calculator on their armory found here: The Armory, looking at the underlying code, we can find the new arena point formulas used for 2.2.

However, just comparing between mmo-champions 2.1 calculator, and blizzards new 2.2 calculator. A 2000 rating team in 2s and 3s goes up by 100, and about 30 in 5s.

Direct extract from http://www.wowarmory.com/layout/arena-calculator.xsl

Rating to Point formulas

function pointCalculator(theRating, theSize) {
	var thePenalty;
	if (theSize == 2)
		thePenalty = .24;
	else if (theSize == 3)
		thePenalty = .12;
	else
		thePenalty = 0;
	
	if (theRating <= 0) {
		return 0;
	} else if (theRating <= 1500) {
		temp = 0.22 * eval(theRating) + 14;
    	return Math.round(temp * (1 - thePenalty));
	} else {
		temp = 1511.26 / (1 + 1639.28 * Math.pow(2.71828, (-0.00412 * eval(theRating))));
    	return Math.floor(temp * (1 - thePenalty));
	}
}

English version:

2s get 76%, 3s get 88%, 5s get 100%

if your rating <= 1500
points = 0.22 * ( your rating ) + 14

if your rating > 1500
points = 1511.25 / (1 + 1639.26 * ( 2.71626 ^ (-0.00412*(your rating) ) ) )

or maybe that isn't quite "English", but anyway

Pulled out formulas from mmo-champion, and chucked the values in excel

Now those are 5v5 values, for 2s and 3s, the coefficients have risen as well, so they will see more of the benefit
