With the new expansion coming out, what better time than now for a revamp of LFR?

This would be pretty awesome, and I can't really see any downsides.

I can only assume there might be technical problems on Blizzard's side implementing it, but only way to find out would be submitting it to the forums.

It might cause a further shortage of tanks and healers though. I feel like many people only queue tank/healer for the quicker queue and this would remove that incentive as they can just queue DPS and play an alt. Longer queues. I dunno...
