Would it be possible to have objects for the name/health of each raid member, that looked for a negative change in health and flashed the name bright red for a second or two if their health dropped?
That way you'd see directly where people were losing health... though you'd be confused at times by effects that drain a player's own health like when using Conjuror Shards and other health -> power tools for example.
Still it might be useful... just an idea.
