Implement a Raid item level limit
Maybe to keep all the raids alive and not just facepalm after a new patch with new raid is introduced i was wondering, maybe put an item level restriction on a raid. For instance, Karahzan - when a player has all equipment slots filled with Kara gear level it would have a item level of fully equipped kara gear, once he goes over that limit he wont be able to enter unless he equips the max item level gear again.
This imo would keep all expansion content alive even when all the expansion content is released.
What are your thoughts.
