People wanting more plat, people figuring out Krono were super cheap in terms of plat / rl $ vs actual Sub time it grants, all games going to SOE All Access easier (you don't have to mess with that subbing 1 month then going full krono stuff), etc
Bottom line is that they are priced higher because people are willing to pay more. People pay more because they are swimming in plat like Scrooge McDuck. This is just fact. The questionable part is how so much plat came to be in the economy recently.
being able to buy a krono , get the free AA's and revert back to silver will make the prices go even higher .
Between decent plat rewards for HAs and Teek quests, and lots and lots of high value vendor trash, probably ten million or more plat enters each server every day. What is there really to spend it on that gets it out of the economy? Bazaar does not remove plat, it just transfers it to another player. Expect more and more plat to be in the economy and nothing to spend it on. Inflation is a sad fact of life in EQ.
The market is going to fluctuate based on supply and demand. Besides. If your not comfortable with the price, don't pay it. If enough people feel that way, the price will fall
Plat levels in the game continue to grow. More plat is coming in then leaving the game, which causes inflation. After you use a Krono, it's gone from the game. They don't pile up like plat, they get removed when used, so supply stays in check. If you spend plat on something, it's simply changing hands, not leaving the game. Now someone has to buy these Krono for about $18. If you have millions of PP sitting in your bank, are you going to buy a Krono with some or pay RL $ for your subscription? With Krono you have an item that has a real use/value, even if no one in the game wants to buy it. I bought about 30 of them and will hold onto them until I either need PP or use them for my subscription. If they were selling for 200-300k pp, I wouldn't think about selling them for plat, I would buy more. At 800k pp, I might consider it a decent price to sell them. SoE loves the price being high on Krono, because it's more incentive for people to buy them. The whole point of Krono is to allow people a legal way to buy plat in game. Would you pay $18 for a Krono to sell for 300k?? Probably not, but you might buy some, if they you could sell them for 750k, 850k, 1M plat??
Remove No Trade from most group gear RoF and lower Make Marks of Valor Tradeable Make old raid currency tradeable Sell/buy Krono on a vendor to remove plat from game. Adjust krono price based on smart vendor Code required. problem solved.
Kronos must enter the game through an exchange of real money. That is how sony pays the bills. They can't simply be sold off an NPC. Making other things trade-able would do nothing to address the inflation problem.
Its as simple as you have 4 million pp in game that you in 3 lifetimes of EQ are NEVER gonna spend. Wouldnt you rather spend 500k on a Krono with PP that cost you nothing or spend $18 of your own money? its not really that hard a concept.
