The idea is very vague at the moment. You want more stuff in low sec, but be more clear what that stuff is, how does it work?
Your example is a site that can be attacked for loot but alerts other players. How does the site spawn? How does it alert other players? How does it choose which players to alert? Does attacking the site send players suspect (so that the would-be saviours don’t lose sec status for engaging the attackers for example)? How does the site end? Who wins and how?
Stuff like that.
