well i hate to post this, as it might be an exploit and i do love this little bug. i havent done it on my multibox shamans cuz they arent 70 yet, but when im soloing with a group in normal and heroic MgT, we stand under the candlesticks in front of him. doing so doesnt allow u to use bloodlust which sux, but as soon as u hit an add and it dies, u get big then instantly shrink back down and the debuff is gone. this is because blizzards mechanics dont allow u to get bigger and (i dont know the word) "clip" into a piece of gemoetry. u can try this it works everytime
