I am just going to chime in with a story from a campaign I played in recently:
My character spent 3 turns fencing with a goblin, as both of us repeatedly missed. Me and the DM roleplayed and made it a tense fight with a lot of swearing. It was fun.
Would I want to experience the same thing in a video game - no, because that would just be miss animations. And even if you add more miss animations they are still just miss animations and can't rival what your imagination can come up with.
So I am all for lowering AC of a lot of generic enemies so I don't keep missing all the time.
You don't need to lower AC, you already have at level 1 all at your disposal to deal with it. Use the Sleep spell to immobilize 4 or even more (if they wouldn't have too much HP). Sacrad Flame spell of cleric targets dex saves which means an almost safe hit against sleeping enemies. Just as example.
