As stated, the only way that fixes anything, makes gear irrelevant. Essentially you'd be asking for all dungeons be tuned to the minimum ilevel, regardless of gear. Thus all content becomes "savage" tier.
No I think the solution has to be "give the healers more to do" and not be "give the healer stupid combos". You do not want RNG (even hoping for a crit is stupid) to be the factor that determines if you save or wipe the party. Hence the original proc's for lilies was stupid as well. If "more to do" comes in the shape of healing idiot NPC's or casting debuff removals, that does make more work for the healer, but that's not something that can retroactively be applied to content.
