I loved the idea of Nexus but my one nexus was forcibly made to check the balance by an Imm. Was leveling with some orcs. Evil was weak. Apparently some goodies logged out and evil became strong. I had no idea. I didn't get in trouble (as far as I can tell) but I had no idea (And definitely wasn't trying to kill two orcs when I was at 30%.)
If they just made any shifts automatically pop up "you feel the light get stronger etc" problem solved. That dajd, entropy is retarded and not a replacement for nexus.
