I think Roadrunners spray and pray quote is a leftover from vanilla Freelancer PvPing.
In vanilla Nomad Blasters and Cannons use zero energy so pvpers often use them because they dont have to manage energy reserves in combat. They can use a continuous fire technique.
If I remember correctly nomads on Disco have been modified to use energy and their damage has been altered too so I dont think that is the case here.
Though I dont know that for sure since I dont use Nomads (They dont fit my RP):laugh:
