The elemental oposition system has changed. Dark and light are now oposites, war and water are now oposites too. As a result, pirate and petroleum are no longer rare hybrids. We don't know how SP will handle this. There is also no rare hybrid yet for water/war or light/dark.

To be quite honest, we still don't know all we'd like to about this update.
