Suggestion of Sites

Would like to know of GOOD sites for example class leveling, raiding, Etcetera,Etcetera,Etceteraaa.
All suggestions are welcome for me to researh in my down time at office

I know at least one website that offers really good information regarding raiding and top specs for all of the classes currently available. The site is called Elitist Jerks, and while some of the stuff that they talk about flies over my head, they seem to know what they are talking about haha.

Elitist Jerks
^^^^^^^^^^^^^^^

Elitist Jerks and tankspot.com are both great sites.

Can't really beat these two suggestions from above. If you're a DPSer especially check out the forum for your class and thread for your spec to see if there is a DPS spreadsheet. Those things are awesome for optimizing your gear upgrade paths. Some people hear "DPS Spreadsheet" and they immediately say "OMG YOU'RE ONE OF THOSE HARDCORE WEIRDOS". When really it's nothing like that. Blizz has made the stats so complex in this game that I would argue that you NEED something like one of these in order to be at your best. Who woulda thought that AGI items are better for a DPS warrior in several cases over STR items?!! Who'da thought!? Not me ... at least not until I ran a spreadsheet :-).
