The way people react to being asked to consider other party members seems to be universal, huh. Whether you're as SCH asking SGE's to not overwrite big shields, a healer asking a SMN/RDM to not instantly raise someone the second they fall when the healers are fully capable of doing it, etc., people get real uppity about their own self-importance. Whether you demand it or ask very nicely (even with please and thank you), people get mad real quick. Funny.
