I love many of the new improvements to WoW heroes. The dual spec option for gear sets beats even what the WoW armory can currently offer, which is quite impressive. I've also more recently noticed the achievements section, which can often times can be more of an indicator of a player's worth than their gear.
My suggestion is along those lines.
I like to use WoW heroes to gauge what one should be readily capable of. Gear score is an indicator, and so are achievements. WoW armory also offers another relevant subset of data in their statistics section: number of boss kills.
I was wondering if WoW heroes might be able to find some way to implement that information from the statistics section so that we can have an even more complete picture of someone's character. The more information had, the more we're able to make an informed decision as to a player's qualifications. The less stops we have to make to do it, the faster we can respond and hopefully catch the right players for our raids.
