Wowhead is known for its massive database of everything under the sun available to be found in World of Warcraft. Quests, achievements, items, NPCs, armor, pets, mounts, you name it -- if it exists in game, Wowhead has it listed. But the Profiler is a little different from Wowhead's usual style of database tracking. Players can look up their character, or other characters, and load them into the Profiler for an in-depth look at what that character has done, and what they've yet to accomplish. So how exactly is that useful? What makes the Profiler, in some cases, a better alternative than the armory?
Do you like the look of someone's transmog? If you look them up in the Profiler, it'll show you not just the gear that they currently have equipped, but what they're using to transmog their gear. The transmog list includes links to Wowhead's database of armor, so if you like a particular item, you can easily track down where to get your hands on it as well -- or even find an alternate version of the model using Wowhead's handy 'Same Model As' tab on armor items.
Interested in completing your recipe collection for various professions? The Profiler lists all unlearned recipes, with links on how to obtain them. Missing mounts or pets? You can find that on the Profiler as well. While the Talent pane is limited in its usefulness, its addition just helps round out what the Profiler has become -- an incredibly useful tool with far more scope than the Armory itself. Check out the Profiler over on Wowhead and give yourself a few minutes to poke around -- you'll be surprised at what you find.
