About 52 seconds a go I got an idea.
This whole "invalidating old content" thing, when we get new tiers of content, example: you don't have to do BoT or Firelands anymore, could be solved by turning old raids into 5mans. You could get the same gear, they'd be more accessible and wouldn't die.
Like I said, I have not though this through. Good idea or bad idea?
