Level 40-49
Level 50-59
Level 60

WoW has this and it makes for very interesting games, especially when you get a game and no one has mounts and a lot less abilities.
People who PVP don't want to be bottlenecked into one PVP mode. The Secure and Slaughter modes are just as good as Seal Rock. Wolves Den needs to be available to lower level players.

For Wolves Den maybe remove the role restriction. Just have 4v4 and ignore all roles, just a quick way to get in and PVP.
But first, could we please get a level 60 version of those PVP modes?
