EVE Dev Blog: Carebearing 2.0
Incursions have been a hot topic on the forums, so Team Five 0 decided to see what we could do to shake things up a bit. After collecting a lot of valuable feedback from you guys, we decided to give the spawns more variety, without significantly altering the difficulty of any one spawn. This was done by grouping the NPCs into waves, and moving the trigger to spawn the next wave from an individual NPC to the group as a whole. This will mean that you now need to kill the whole wave to trigger the next one, rather than just specific NPCs.
Other changes will include the addition of Rogue Drone bounties and adjustments to the security status of drone region systems. Read the full blog for all the planned changes.
The new changes are expected to hit EVE Onlines Singularity server in the near future.
