Why not add a way to buy rainbow mog pells?
With the addition of the character change service, there is now a way for a player to buy an account activation that allows an NPC to recognize that purchase in the game.
This could be a way to sell mog pell rainbows to players.
Given inflation being the way it is and Square Enix obviously being upset about that, this would be a way to add an additional optional revenue source to the game. Could even add more items to it.
Yoshida was complaining about inflation in regards to ff14 and then being more reliant on the cash shop than the sub now, cause of how much value it has lost over the years.
