Is there a more annoying Enemy in zombies than these 2.

Are there anymore annoying enemies in zombies than the Vermin and parasites from both maps. I don't know what it is about it vermin but the hit boxes with melee weapons are non existent. This isn't a rant or moan post I am just stating my thoughts. I think I would rather deal with Manglers than I would these pair of little B*ARDS🤣. Anyway enjoy the rest of your day wherever you are.
