None of you can see why I'm so sceptical about those train/troops ideas? Imagine yourself on place of pilot of that train. Having to go from one place to another many many times bringing something, while everyone else is fighting around. Who will agree on that role? And why waste precious server resources (cause the more players are in one place at one time, the more server load increases - you may have 30 players in different systems with less lag than 15 in one place) for that train?
Destructible installations are another bugger cause they'll respawn each 24 hours (our server current restart time, might be even less actially). You destroy it, conquer system and oops - in 10 minutes it respawns again, owned by same faction as before, and starts shooting at you. Logical? Hardly so.
But main reason why I have to reject eon's idea is the system owning part - we have only one home system per faction, not the whole space under its control. Liberty is faction-free (but that's not really important). Anyway, we are going to move homes away from existing systems so that faction gameplay doesn't interfere within NPC activities.
