Yes it would definitely help with the economy, considering the player base being so low and there being a huge excess of items. Supply is really high yet demand is pretty low.

Would be interesting if they made an event or lottery in which you transfer items to a staff/event account and based on the worth/quantity of the items you get certain % of winning and you get rewarded with like VIP or Custom Usertitle, and other prizes. (just randomly thought of this so meh not really a full idea/thought out because it's pretty much 1am and I just saw this post so yeah). Anyways, if there could be some way of sinking items whether it be via an event or w/e then it would help.

However, considering the low player base, I doubt there would be enough item sinkage to really impact how the market currently is.
