Colorless Souls are camped 24/7 on Shiva by multiple groups. It might not be so bad on lower population servers, or ones with less Japanese players (for nighttime farming), but it's awful here.

The entire VNM system is garbage. It was never a good idea. Not only do you need 75, which is more than the usual 50 for the 2nd Empy upgrade, but the respawn times, methods of popping, and competition are all harsh.
