Paladins and Druids to get a Lift

[Warlock]

Thanks for the Greater/Flash comparison. I still don't really see it, and probably won't without playing a Priest or Shaman and seeing a fast heal in action as the caster.

Are there any mods that allow setting cancellation of heals based on missing HP rather than by percentages of the target's life and/or to customise the cancellation threshold by spell level? The behaviour I want from low rank HT used to chain cast on a raid buffed tank is not the same as that I want from higher ranks or casters.
