I totally understand where you are coming from
I just approach it differently. I believe the item would be way too powerful. It would open a lot of ways for exploitations. And therefore the price should be very steep. Now that I think of it... it may be a perfect item for the BMAH. There, items some players really really want go up to insane high prices.
Like I really really wanted a brawler's guild invitation. Paid almost 70k for mine, and was happy to snatch it that cheap. Since most went for up to 300k. Was it worth spending that gold? Hell no... lol
