Do any of you actually army build hordes?

With Age of Sigmar being a thing now, it inevitably brings up the possibility of Skaven. Which got me thinking I'm gonna need at least 3 clanrats for every Stormcast. Which got me thinking that's wildly impractical. Which got me wondering if anyone actually army builds the current horde factions like Tyranids or Guard. And I don't mean a couple here and there, or a "squad," I mean a whole ass biblically accurate swarm of them. I've seen how many space marines you people have and I need to know if anyone has that same energy for the other factions.
