Edit: Due to some duly noted confusion, here's an edit. AC items should still be 1st use CHARACTER AVAILABLE 2nd use ACCOUNT-WIDE AVAILABLE. They just should be UNTRADEABLE TO OTHER PLAYERS after their first, initial chaseform the personal shop.
Please make all AC items UNTRADEALE TO OTHER PLAYERS once bought from the Personal Shop. Scalpers and trading barons are a leech on the economy and should never exist. Only the people buying AC scratch should be able to sell AC scratch items. Lock all AC scratch items to account-bound status once bought from the Personal Shop. Retroactively.
This will not affect supply (of new AC scratches). All people buying AC items will be able to sell them. This will eliminate buying and reselling at 10x prices, since they will now be account bound when bought. People wanting to convert AC items/real currency into Meseta will still do so by buying AC items.
This will not change any behavior of the AC items. As they exist right now, the first use binds it on your character, the second gives it to your account. People who bought and used an AC item they do not like will not be impacted, since it's already used on their character. Buying and re-selling of extra AC items not for personal use does not have any role in the original design of AC items.
This benefits both players and SEGA. Only way to turn actual currency into in-game currency will be through AC Scratches, so SEGA gets paid. Players will no longer have to deal with a small minority fucking up everyone for personal profit.
There are literally no downsides to this solution, and it will breathe much needed life back into the economy the moment it's implemented, as soon as next week's AC scratch drops. Run it as a trial solution if you wish, but don't let the economy get any worst or there will be NO recovery. Just like what happened when you guys released cradle.
Extra stuff: Yes, retroactive implementation fucks supply of old items. But get this. The scratches are over. There's meant to be no more way of procuring them anyway. And if you BOUGHT those AC items in the first place, FROM SEGA, you'd have no problem selling them now. But if you are a filthy scalper who bought them out cheap for reselling now, you deserve to be fucked. Unless I'm completely missing something, this is a necessary solution that should have been put in place since the start of the game. Just like how red-boxes should have never contained meseta in the first place.
