Okay, sounds like you don't have much healing. Viable choice in 5e, though works better if supported by being high stealth or something else to help avoid needless encounters.
Great, you have an opinion. Of course, that doesn't mean any other player needs to agree with your opinion. So it's rather irrelevant.
Okay, you're not the healer and you don't spend lots of your healing in combat unless someone drops. Wouldn't be particularly noticeable if you weren't posting about it. At my table we'd really hope you have a character personality and picked a paladin's oath that goes along with it. A tough driven pragmatic oath of vengence we'd all go "oh yeah, that's perfect, clean up your own messes" while a virtuous or holy oath of devotion we'd think you're meta-gaming.
As a side note, if we mentioned that as front-line melee folks, you and him are protecting the squishier members of your party, but the little healing the party has goes twice as far because if they get hit they take full damage, while he only takes half due to resistances? So he's doubling the effectiveness of the healing available.
