Cripple MOAB is a support upgrade, not really something you would make too many of. I personally like to have 2 of them past round 100s, so one can set to hit first so it slows the line of ZOMGs, while other locks a strongest one in place.

Also, you wouldn't be getting cripple MOAB until you get past round 90s or so, which by the time would't be much money to spend thanks to the factories and supply drop snipers.
