In all seriousness, I understand the frustrations completely for those who have to deal with this in roulette.

As a PLD main, I tend to gauge the party first (What jobs do we have, how much dps are they putting out, can our healer really keep me up?)
If I think that the party can do it then I do a mass pull, if I was wrong I apologize and start pulling in smaller groups.
Seems that many tanks besides myself don't do this anymore sadly.
