Ok, just to see what would happen I took the shield off my large train. Mainly to see if I could do the VIP - Organisms run without one.
I found, very much to my surprise that, any NPC with a wasp cruise disrupter can stop me.
Regardless of where the missile hits.
So it appears that the shield is what is stopping the original disrupters from working.
So either the shield shape needs to be altered/looked at or we remove the shields from all transports and trains.
Before I get lynched for that last suggestion heres why:
1) you'd have to use a frieghter/armoured transport to trade in the borderworlds, mainly because they have shields, CM droppers, more weapon mounts and they have a massive number of weapons to choose from. This would also mean that people would start to use freighters more often.
2) traders would need an escort in most systems without tradelanes, this means an escort faction would be able to exist, merc factions would be able to get jobs and it would increase RP possiblies.
3) we can scrap the shield battery supply and then double the nanobot supply, meaning that the transports and trains can survive longer even without shields.
