Really promising.

This is an awesome app for World of Warcraft players, it gives you the tools to check out everything the same way you would do with the official armory.
It has an exclusive Calendar views, where you can accept your invites right from the iPhone/iPod Touch.
My suggestion for Blizzard is that they include the funcionality to Create Calendar Events and Send/Check Ingame Mail - this would make it 6 Stars.
