Just an idea...

With the server not progressing (from the looks of it) with new content, why not have it to where the sleeper can spawn again?
I understand that it isnt classic. However, it would be awesome for the people that havent ever experienced a warder kill, or witness sleeper go in his rampage to see it.
Maybe make it a yearly thing? 6 months?
If that isnt feasible, what about having the Wardens pop during draft week and allow for more targets?
