What I hate is even if you like being a healer, healing spells just aren't efficient and you're better off casting most anything else outside of the occasional level 1 Healing Word to get a fallen guy back up for a round.
But that ship has sailed, and when I complain about it, I keep getting told "that's a feature", lol.
Yup that's a problem with 5E imho.
Had a cleric last night cast a clw spell that fully restored a fighter.
Technically you can do tgat in 5E but +1 to hit and 1d6 damage is a lot different than 5E Mook type monsters.
