The problem that has been outlined here is not with blind jumps, but with the fact that all Nomad ships use the same jump drive. What we need is three versions, just like the humans have.
Snubs get a jd that cannot jump people with them but maybe has a fast charge.
Gunboats and cruisers get a jd that can jump people that are 100m away from then at a longer charge.
Marduks get a jd that can jump in a large radius (500m?) and takes a few minutes to charge.
I talked to Huggie about this and we basically agreed on these points. You could turn the Nomad engines into jump drives instead of the cm, Spazz. They can't be unmounted so nobody can do mischief with them.
