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.
It's almost as if the player were to actually use his brain and try to make a party that complements itself with synergy and utility and use the tools at his disposal to deal with these encounters he would succeed. Instead I guess what people want is just a wack-a-mole simulator where you only auto attack enemies and they fall dead without putting up a fight.
That would probably "entice" a lot of players, let's just ignore the soul and lore of the game because they're completely irrelevant I guess.
