Blizzard provide a handy ilvl display in your character window. Useful for knowing if you can get into HC's or even just how well your gear is coming along. It has one flaw though: it counts what is in your bags as well as what you are wearing.
This addon allows you to answer those all important questions
"Is my tank gear as good as my dps?"
"Is my PvE as good as my PvP?"
"Just how much does fishing equipment hurt my ilvl?"
The original blizzard figure is relegated to a number in brackets, with the other number being the ilvl of the currently worn equipment. The screenshot probably explains it better than I can! :P
You can also get the addon to report to the chat window as well using
/currentilvl or /cilvl
Now hooking paperdoll function rather than catching updates (thanks to ballagarba for locating the function & providing example code) - huge performance increase and inherently prevents bugs like the one fixed by v1.2
Simplified the mainhand+offhand vs twohand code
Fixed cilvl incorrectly displaying on rage/energy line for feral druids in shapeshift form
