The thing is, if both nuke and novax are not assisted then novax can block the nuke each time it launches off CD on 20x20 map.
Giving your team 10 minutes to make smd in each base. And forcing opponent to make 2 nukes to get around it.
The mass cost is also in favor of novax netting you 2k mass advantage with each body blocked nuke.
And like I said, mods said it's exploit to block nukes with novax no matter how. Unless you somehow managed to ctrlk satelite over the SML, but that requires a lot of luck due to changes in how the wreck falls now(it sways a lot and basically it's impossible to aim due to RNG implemented)
