I agree with this, conditionally:
The only tradable items, are limited time only items, such as christmas items, but limited time as in only has been for sale once. Not like a santa hat that is sold every year, but rather a santa-hat-wearing-obama-cardboard-cut-out that was only sold on the day of 25th December 2017 (Or something similar).
This would get rid of the RNG or Pay aspect that people don't like, while still creating market that other people want.
A win-win in my eyes.
@macdguy Do you think this is a good resolution?
