No, that isn't it at all. It was meant more humorously but I guess came off wrong.I think if this is your reaction, your motivation for using this tactic is coming from the wrong place. It sounds like this is less about playing the monsters efficiently and more about getting back at the players for a perceived slight, which is not a foundation likely to result in a very good time being had by anybody.
I just mean that tactics the players use, like focus fire, wolf-packing, force separation, etc. can and will be used against them. If they don't like that, I don't know what to tell them other than the monsters defending themselves in their homes will use any and all means to defeat the PCs just as the PCs will use their best tactics, features, etc. to defeat the monsters.
