Not True. Parsing is rampant in extreme and savage content as well. So much so that there is a website that publishes it for those that want to see and be ranked. You can create an account, and opt out of your information being seen, but chances are, if you've done an extreme or savage, your character's name is on here somewhere.

In fact, it's not uncommon for people to decide if they want to raid with you, based on this information. If you aren't on there cause you opted out, they won't raid with you. Or, if your dps is not to their liking, same deal. This is absolutely true with statics recruiting, and I would venture to guess true to a lesser extend in random savage pugs and extremes as well. Example: Person suspects you are doing bad, person goes to above website to search for you, person either A) finds parsed information on you, and makes a decision on if you are bad, or B) doesn't find information, assumes you opted out, and assumes you are bad.
