Entropy was really interesting with a huge playerbase making all the cabals full. I remember mirror image and however they changed room exits being tough to deal with sometimes. I do not know what all their powers used to be, honestly. I have heard they do not have excellent powers now. But if we went to 4 cabals and let Entropy be one with a revamp in powers then they are opposed to which.. Empire or Tribunal? How would you set it up? I think if we were to cut that Entropy would go. But who knows? People who played the old Entropy used to love it and were mostly excited (and then disappointed) by the new Entropy, from what I gather.
For my way of thinking, a "mage cabal" has to be set against the Village and has to have some way to let you last more than 2 rounds against a berserker. For old school masters that was despoil, right? For Nexus it was the bond.
