Clerics, paladins, and some other divine classes get Channel Energy, which heals the entire party as a standard action, and which has some feats and items which boost it further. Turns out that healing multiple people for one action is often worthwhile, even if healing a single person for one action is not.
Sadly, most if not all life drain effects got hit with a nerf bat - they only provide temp HP, or restore limited health per day (!). It's a shame, because life drain is one of my favourite concepts, and it's kinda weaksause in PF 1e.
