I tend to passively heal myself as much as possible, it's a lot of healing wasted from lifeblooming myself too. I prefer having the spot healing on those 2 people and I cover the 3rd person with cenarion ward usually. Only place where I lifebloom myself would've been 3rd boss if I had one of the lifebloom people press something big to catch up on myself, or in general if I have a big bad dot I can't passively outheal. Both gameplays are equally viable and both can time same keys, so it's up to your own preference.
