I would expect you to play a Paladin.
If you have healing magic available, heal by all means. But don't save a spell slot "because you think someone will go down" imagine how your paladin would act... if he is naive he'll probably be charging in wielding his one handed melee weapon that he has because shields are awesome in 5th edition and smite something, or divine favour.
I feel for you because there are so many classes who can heal and half of your party is doing "1 job" as warlock, wizard and sorc. If only 1 of them realised how good Bards are in 5th they could heal too!
