As my gear has gotten better, on some single-target boss fights, while with various different tanks (assassins, powertechs, and juggernauts), I sometimes steal aggro from tanks midway through the fight. I'm not talking about fights with aggro drops or weird mechanics.
In WoW this was a sign of 1) a very high damage character as compared to the tank or 2) a tank with poor threat.
What do you guys think? Is it OK to use this as a measure that my damage is pretty good? I'm trying to find some meaningful ways of gauging my personal damage since I've played tanks and healers in prior MMOs, so it's pretty cool to try something new. Thanks.
