I think selling an item that would TR you but allow you to keep your raid completions count going would be a great idea. I know I would pay quite a bit for an item like this and it would make me more likely to want to keep playing the game for longer. At times I feel trapped by my desire to wait for some multiple of 20 quest completions before TRing, if I had the option to just save this progress I know I would TR more, have more fun playing, play longer and spend more money on playing.
