Amanna is the latest blogger to bring up Warcrafter, a nifty little online application that is basically the Armory on speed. It'll not only pull up your character, your gear, and your talents, but it'll use all of that information to calculate everything you'd ever want to know about your stats, including DPS, crit percentage, spellpower, and even where all of those things come from. It'll even go into your spells, and calculate the average heal or average damage of your most-used spells and abilities. Warcrafter tells you everything it can calculate about your character, directly from the numbers pulled out of the Armory. Fascinating to see.
There is also a sandbox page, which is everything an aspiring theorycrafter would ever need to make up the character of their dreams. Punch in a class, race, and gear, and then go to town shifting around buffs, weapons, talents, and anything else you'd want to check. Cerberus is an attentive creator, too-- if there's a calculation off or a piece of gear missing, he seems more than happy to add it in. I only hope that we don't crush the site with our exposure.
The sandbox page mentions something about "locking" the character, and it would be cool to have a quick permalink setup for created characters (we could have someone show off all the buffs/gear needed to get the Ghost Wolf taming cast time down, or show off the highest possible spellpower available in the game so far). But other than that, Warcrafter is a great piece of web-based software. Very cool way to inspect every single aspect of your character out of game.
