Real early on we had some problems with clothies drawing two or three random scarabs, particularly priests with healing aggro. As a healadin, I never minded so much, just let them nosh on me and switched aura to Concentration for 100% pushback resistance... I think that what our pally OT (when we had one) would do is run from person to person and consecrate the scraps rather than stressing overmuch about getting them all from the beginning.
