I suppose that takes care of the question, then-- there's no reason to take an army if you automatically lose.
There are inexpensive means to build an Apocalypse army. Heck, a Baneblade is 500 points all by its lonesome, and adding that to an existing 2000 point army leaves you with 500 points left to build. That's like two or three squads, tops. There's no reason you can't build the 1000 points for Apocalypse for about 200 USD, I don't think.
The thing that I've noticed a lot of people fudging is the 3000 point minimum. Using the Strategic Assets and superheavy tanks in 2000 points is a fair bit of fun, and the game doesn't last more than an hour since, well... baneblades are rather destructive.
