That latter portion being so small and thus breeding so ambiguous in it's cost is just yet another unfortunate symptom of so little of our healing, if optimized, having any opportunity cost at all.
Why they decided to go that direction (of too much free healing or too little to heal), such that healers' maximum and solo offensive output would have to be squished in balance and CC and further tank mitigation at trade-off could have no real reward... well, that's the greater mystery.
