Giving CS for actually holding a moment
Hey, I can fully understand that balancing is one of the most complicated parts of every engine. So I thought about your words, that you want collectors not flippers on TS. So how about getting CS for actually holding a moment?
1 point a week, 10 points a month for commons, 10 points a week, 100 Points a month for rares and if you are realy into it double the amount if the moment was from a pack or a reward and never sold. Voila.... you get what you want: collectors.
