I would think it's common sense to look at your healer's MP and refrain from pulling a boss or packs if they're low on MP, but apparently common sense is not that common at all. I had a tank pull Ser Adelphel in Vault once, when the WHM was at around 4.4k MP, then bitched about the WHM running low during the fight.
Also, you're in a friggin' party. You're not playing solo, you're working with others to accomplish a common goal. You're supposed to pay attention to them. That's kind of the definition of teamwork. If you don't like that fact, there are tons of single-player games out there, and you shouldn't be playing an MMO.
