your healer may hate you.
just because you see a well geared, experienced tank grabbing ALL the trash in a dungeon and dragging it to one spot so the dps can aoe, that doesn't mean your tissue paper wearing self can do the same thing. Benediction is NOT meant to be used on trash pulls. if your healer has 10%mp after a trash pull, you're pulling too big. period. and don't take off and do it again when the healer is under 50% mp. you may feel like a god, but you're just a goof with inferior gear. stop it.
