PartyHats.

I've been wanting to upgrade my white to a blue for almost two years now, but can't due to the ridiculous street prices.

Now...

I think JaGeX should let the Phats update more frequently so they can lose demand faster (Due to players' lack of being able to afford them) eventually leading them to fall in Street Price, drop in G.E. price, then get bought out again. But this time, in different hands of hoarders - Mainly the collectors.
Would this be a better situation at all for the Economy if all that were to happen?
No.
So truly, it's best for JaGeX to just leave well enough alone & watch it playout from here - No matter how bad it gets.

__________

& One more thing.
To limit rares, that means the extras would need to be removed.
How would this be done exactly?
Transfer all the extras to the G.E. for Max, Lowest, or Mid price? Most likely, right?
Well, that'd make a first come first serve to those who sniped them.
...But...
Maybe a sniper sniped two? How would the G.E. determine to ONLY sell one to one player through the G.E.?

As you can see, this process seems EXTREMELY difficult to fall through successfully without flaw.
This could explain why nothing hasn't really been done about the D'Item Market for so long - Mainly due to a finding a fair solution verses an achievable solution through Java.

Regardless however, RWT IS affecting the Market heavily. It's only increasing to grow as well.
The third richest player was banned some odd weeks ago (Alish...) for RWTing her Phats - As you may or may not know.
This obviously brings attention to JaGeX's eyes I'm sure.
& I guarantee you they're going to find a way to stop it.

JaGeX says RWT ruins their game.
So why should Discontinued Items be an exception?

Jagex hates discontinued items. They posted somewhere that their goal was to eventually rid the game of them. They aren't going to make it easier to trade them when they don't want them in the game. They're going to make it as hard as possible and they're gonna ban those members who have them without a 2nd thought.

Just my 2 cents.

If they stop RWT, a lot of their business would go out.
Think of all the companies that are in business because of RWT, and all of the people that sell accounts for money.
It seems nearly impossible to stop.

I agree with Echoes.
People who own partyhats bought them off other people because they bought RWT'd gold from a site. Once they quit, they will pass their PHat onto another player who also paid for his GP!

Yes, the prices are quite high with Phats. But it is to be expected with the rarity on it.
