"Spotlight" a particular mode of PvP
In an effort to make all the various modes of PvP more active (secure mode, slaughter mode, and wolves den), the development team should consider the following feature: Spotlight.
The spotlight mode will be displayed under the PvP window and/or Duty Finder. When playing games in the spotlight mode, the rewards (PvP exp, wolf marks, and law) will be increased (maybe by 1.5x).
The spotlight mode could be determined by a lot of things. Could be a fixed timer, so every 24 hours it changes randomly. It could be a rotation, where it goes in order where the spotlight is. It could also be based on what mode at the current moment doesn't have a lot of players.
Another suggestion, while not related to Spotlight, could be to make a secure/slaughter/wolves den (hard mode), where the content is made for level 60 players. And related to Spotlight, it could alternate between hard mode and normal or both be active at the same time.
