Or maybe let's make invasions sometimes spawn along with their enemy faction's invasion (you know, battles of armies). I mean if an enemy invasion will summon near you it has low chance to summon their enemy invasion too (i.e. you're Dunedain and meet Gundabad invasion and there spawns Elven or Ranger of North one to fight with orcs) so you can help your allies to defeat enemy raiding party. Something similar was when Frodo and Samwise were in Ithilien, the Harad "invasion" was coming and Rangers appeared and "invaded" too. In more simple words: rare skirmish of two armies ^^
