Thanks all! Some great answers here I didn't think about.

Now that I think about it on my Legacy server there are tons of Max Level Crafters (most of the Max Crafters I remember from the early days). It makes sense that if Legacy servers have so much competition it drives down prices.

(Same for Max Level Gatherers I suppose.)

And, yah, on Masamune at least there is very little RMT spam (it used to be hard to create a new character on this server as well).
