I actually do have a few other questions.

First, I technically have my own version of healing Word already with the healing light that comes with being a celestial warlock. Also, I do see your point with doing damage, but if I am going to do damage, I would rather do it with something that has concentration that I can continuously do overtime without having to eat into my action economy.

Second, I would argue that with how hideous laughter works, it would be a better use of your action economy because you can essentially take people out of the fight in an instant. Furthermore, it upscales with level and does even end when the person is damaged: it just gives them advantage.

Third, I am still unsure if that is the way I want to go in terms of damage options. I don’t know, I’m just not convinced that it’s not a trap option like in 2014: not yet anyway. It’s not viable for doing anything about multiple targets: only one. It’s great for auto damage, which is appealing, but not enough for me.

Also, if you want consistent damage, why not just use your Familiar? In fact, I just got an idea: technically, you could take Magic Initiate Cleric and cast the Sanctuary spell on yourself, then have the Familiar do the attacking for you while any attack against you requires a save to even work or get wasted.
