Disciple of Life does add a little extra boost to Healing Spells, and they will become more effective with higher level spell slots, but overall it's still not much more effective than potions that can be thrown across the board at allies.
Because they are trying to make the healer somehow valuable, they've made it so that their healing is super powerful.
I have a little problem to fit those two sentences into single mindset ...
Can you choose, please?
Either potions are striping Life Clerics of their purpose, or LIfe Clerics are ridiculously powerfull healers ... both is litteraly impossible.
