I use it on the smash after p2 swords, ukehl if it's up and thundercloud stacks. Place before it comes, detonate after the damage. In a real emergency I just place->detonate. Heals more than enough. Honestly I would class it as an instant. I understand what you're saying, I just don't think your point is completely right.
