Healing is a team game, when the whole raid stacks for feud, you see healing rains go down, you see efflorescence, you see circles. A dozen people toss their AoEs, while each one only hits for 500-1k ticks, their combined power heals the raid through the AoE. If everyone decided "it only ticks for 500 it isn't worth it," you'd be trying to spot heal 25 people through what is honestly just way too much AoE damage to keep up with.
Other fights might not be so demanding, but that doesn't make efflorescence any less than our best AoE ability. The HPS is also insanely efficient, the cost of an instant cast swiftmend can rival HT in direct healing, and then turn into our strongest AoE heal for free? One GCD and almost zero mana can turn into several tens of thousands of healing - you don't get that with any other spell.
Hell, our DPS shaman drop healing rain during feud, every little bit helps.
