While I can spout off such things as what is the basic stat you want (ie Agility, Strength, Intellect) for each spec a lot of the “finer” details I have to research. So I thought I’d share some sources I currently use.
PlayerScore http://www.tentonhammer.com/playerscore
This is useful for determining where to concentrate on.
Used to be Gearscore add on, It’s now a website as well as an Addon. It now gives you a PvE & a PvP gearscore. It takes into account achievements as well. For example, I may not have great gear, but if I was skilled enough to do the encounter with lower gear then it means I can make up for a lack of gear with skill & precision timing & it takes this into account and gives bonus points.
One complaint I have is number inflation. I remember when a 3.6k gearscore was high. Now gear scores are over 10k.
A large part of the gearscore problem was Pick Up Group (PUG) raid leaders would overvalue content and would not take raiders with a gearscore under the number they chose, which was a raid leader issue and not a site/add on issue.
