Was thinking about giving this game a go, plan on playing trial and see how it goes but assuming I like the game..

What's the gold sink in the game? Housing? How much gil for pre-raid bis items?

Any info appreciated

Gold sink in the game is glamours (i.e transmogs) and housing.

Pre-raid bis costs about 5-10 million depending on your luck when trying to pentameld your items.

Economy in this game is pretty well done
