You are right. The reason to fight over resources are somewhat.. Meh.. That doesn't mean you can't do it.
I suggest that they add a few rare resources with the totem expansion patch. That way they could get some fighting started. (But this game wasn't meant to be the siege game everyone, apparently, think it should be.. Might wanna consider that before you start getting too much PVP IS TEH ONLEH THING..!)
I know Lux Arcana holds the trashpile, close to us, very dear and we don't like strangers on it. Even though trash is easy to access..
