At this point the druid goes bear and picks up the new bloods and you just need to kill the boss before he becomes overrun.
As others have said time to kill amalgamations is the significant factor in determining number of bloods. The only other thing I would say is on each roll you should try and get the amalgamations to absorb some bloods before they are thrown off. During a roll we tank the amalgamations on the opposite side of the dragon from the side you are stacking to roll, then when we are ready to roll our spriest lifegrips the amalgamation tank. If he is stood correctly the amalgamations should then run over the pool of bloods left over from the previous plate removing most of them. On the final roll this can remove significant amounts of blood.
