There actually ISN'T a pink bow available at this time for under 10K.
And for the record, I LIKE the fact that I can use affordable pinks in this game and let the "elitists" go for mythic, etc. I don't think this is a bad thing. If there is too much of something, people shouldn't sell it. An item's value is what someone will pay. I think we went down this road when PL was L50 and the Sunblessed Bow dropped "too easily". I think that's nonsense. Value is not based on function. A value is not absolute. A value is a changing concept in the mind of the one who desires a thing. The one who is selling does not value the item, he values the gold he can get for the item. And thus, through negotiation, they either work it out or they don't. The seller can't FIX a value on a thing because he is not the evaluator. He only knows what he wants, and it not the thing itself. He wants gold.
STS isn't going to mess with the market. They introduce new items and let the gold pieces fall where they may.
