I didn't play a cleric in our first campaign. My buddy did. We were stuck in 3E combat healing mentality where cure light wounds was your only low level option.
After playing a cleric myself, I've changed to the healing word is superior camp. I've done this for reasons other than action economy. In 3E/Pathfinder the cleric (especially at low levels) was a fairly weak combatant, so focusing his slots on healing and removing debuffs from stronger combat classes like martials and arcane casters was an efficient use of spell resources given the difficulty of our combats. That isn't the case in 5E.
In 5E the cleric is as strong in combat as most other classes. So focusing spell slots and actions on healing alone is an inefficient use of spell resources. Healing Word allows the cleric to heal, while focusing potent combat actions on attacking, thus allowing your group to end the fight quicker. I was quite surprised when the party was down to two members out of five (the cleric and warlock/fighter) to see the cleric cast spiritual guardians, spiritual weapon, and start casting sacred flame while wearing +1 half-plate with a shield and decimate the room of enemies. I had picked her up Resilient Con and boosted her Con to 15. The cleric tore that room up at 7th level. It was illuminating. Now I understand why their spell list is limited. You have to be careful giving clerics any more than they have. In 5E the cleric is a power class and you have to be careful with it. You give it too much and C-zilla is back.
Better to build the cleric for combat and use healing word[/I in 5E than cure wounds. You can build a crazy tough cleric in this edition. You could build a pretty tough cleric in 3E/Pathfinder, but martials and arcane casters were still for the most part tougher for most levels. In 5E the cleric is one of the stronger classes from beginning.
Clerics can do a lot of damage when the sh*t hits the fan, it takes them a while to wind up though. I'm playing a War Cleric and when you have time to wind up all your spells (ie, a big fight) you can wade in and kill a lot of things. Most of the time though he is a attack magnet (high AC, bonus action attack, dodge action).
The Light Cleric is a serious damage dealer class with Potent cantrips, fireballs, and spiritual weapon bonus action attacks, without the same wind up period (Round 1 spiritual weapon + potent sacred flame, round 2 start dropping fireballs - spiritual weapon cleans up what survives). Just make sure you have Elemental Adept (Fire).
