Or maybe as a tank I'm just not a fan of wiping over and over because the rest of the raid can't soak meteors?
Or maybe I'm not a fan of being declined (or told not to sign up in the first place) for raid groups, simply because I haven't already beaten an encounter, when the only reason for me not defeating the encounter is down to the performance of the group as a whole.
Curve is not the indicator of player competence that people think it is. Someone who dies in the first 30 seconds of KJ still gets curve if their group beats the encounter.
