It has been awhile since incursions in highsec dropped from 3 spawns to only one single spawn. However sometimes you get the single spawn and an invasion in the same constellation/system, it is funny when it happens, and it caused me to have an idea.
Why not allow incursions to spawn in 3 points at once like they used to, and keep the invasion spawns the same? And when they meet, which they will occasionally, have special sites where you have Incursion Sansha and Invasion Triglavian rats fighting each other, and your task is to kill both fleets or perhaps destroy crucial infrastructure for excellent rewards.
That way you can buff highsec incursions to the level that they were, allowing newbie communities to form and do them, without the sandwich that can occur when you only have one spawn. And allow for the two factions to fight and for capsuleers to kill two birds with one stone.
EDIT: The additional content is a bonus, the main argument that I have is to restore the incursion focus spawns to 3 at a time in highsec, if no extra content is added that is fine by me, but having 3 incursions at once + invasions allows for lots of content to be had by highsec residents across highsec.
