Luckily, there is a solution out there that will please not only the people who have the items but those who want them as well!
As I've been suggesting for years, we need a CI/RIG that is released in the cash shop as individual items as well as the actual chance itself - take a gamble, or buy the shiny you want right now instead. What you do is you put gaia cash prices on all the items, so the pet might cost 25-50 dollars but surprise, it won't cost 2 trillion in the marketplace. Why? People normally price things according to the rarity and expense - the more expensive it is to obtain it, the rarer it is, the more money. Thus, guaranteeing every RIG/CI item will be available to people for an entire month destroys the concept of hoarding and price gouging since you can just buy it.
A second option is putting a cap on how high certain items can go according to the rarity of the item combined with common sense. Sadly, the users in general should not be allowed to have complete power over items.. seen the result around here lately? In 2012, having 100 billion made you a super rich Gaian. Now, even 1 trillion is considered "semi-rich" -what's next, 1 quadrillion? Cap new items at reasonable prices, enough to make a profit but not so much profit it costs an arm and a leg and the rest of the torso! This would be something along the lines of the most rare 5 items of a CI/RIG being priced at the higher end around 100 billion and everything else underneath until we can get inflation under control. A common drop shouldn't be listed for 250 billion with NOBODY willing to negotiate or deal with it for a decent price. The system is broken and it needs to be fixed.
We need more ideas and less people saying leave and go somewhere else, because frankly if enough do it there won't be a site here in two years. We need to fix the problems, not ignore them or pretend they aren't problems.
