Suggestion: Mystic crafting
The mystic forge and the RNG behind it is a massive gold sink for the economy. In changing this, the whole game economy would be undermined and there would be a great excess of gold. In following, because there is more gold (that isn’t being constantly removed from the economy) inflation would be a huge problem and thus people with less in-game gold would struggle to buy anything off of the TP.
Besides, the majority of the RNG aspect of the MF is rolling for precursors. With the HoT expansion, we will be getting methods of acquiring a precursor that avoids RNG.
So no, I don’t support your idea. I think it causes more problems than it solves, although I do like the idea of having easier access to the equivalent of the MF.
