Indom is aoe healing that has an opportunity cost (losing Energy Drain potency). You do not want to use it if you can handle the healing in other ways (e.g. Whispering Dawn, Fey Blessing, asking your AST co-healer to use Celestial Opposition).
Celestial Opposition is free aoe healing that is at the top of your priority list. It's something you want to use over anything else because it's free.
The argument that the healers play the same way is short-sighted and shows a very shallow understanding of how each healer works individually and as part of a two-healer team.
Where do you draw the line to decide what is "properly utilised"? Is Deployment Tactics not properly utilised because I only use it once in Hades Ex?
They are options you have to handle different things and the way you utilise them is up to your own judgement.
