To add to Cynfael's point, a "decent" paladin tank with i125-130 should be putting out 170ish DPS. Decent Blm should put out 300-400, and good ones push 450+ depending on the fight and presence/lack of echo. 120 is a DPS rate achieved by people below lvl 50, let alone ilvl 90...... A friend of mine went into DF t6 a few months ago and he was out-DPSing the other two Blm combined. I think it is a combination of ignorance and apathy.

Do parsers get abused? Without a doubt. Are parsers a great way to inspire improvement and see if people are trying to get carried? Also without a doubt. A parser is a tool, it all depends on how you use it, just like any other tool. A gun can be used to kill in cold blood, or to protect people. There are millions more examples. Pick your favorite.
