VR didn't exist in C1. While I was surprised I adjusted my gameplay accordingly and have had to make a strategic choice about my style of play.
I would like to see dwarves producing Soul / Spirit shot and the other classes consuming it ... dropping the base price of D-Grade items in Giran, Gludio, Gludin would be the best way to stimulate that.
This also eases the transition between D-Grade and C-Grade as by creating and crystallizing dual swords ... i.e. SOR*SOR you pin the C-Crystal price to a derivative of the D-Crystal price.
Mats, Crystals and the Giran shops are the engines of the L2 economy for a low population server.
Increase Spoil or drop rates for mats and lower the price of the D-Grade equipment found in the shops and you have a chance at a sustainable economy ... until B-Grade

I have no idea if that is possible but man I would love to see a Tarbar cost 1,000,000 adena instead of the 1,540,000 last time I looked.
