Making the server a Classic Server would fix the Economy's problem. Most oldbies quit due to not wanting to pay the Gold Subscription.
So take away the Gold Subscription for GK, and you have TONS of players with Classic Accounts. This will support the return of players who don't want to pay to play. This, in turn, bring more items back, and more items into circulation drives down the cost of other, rarer, items. Economy fixed.

Good Reason's:
Many old player's with items and such will come back since they dont wanna pay for Gold
More people to trade, stimulating the economy.
Bad Reason's:
Stefan and Stephane not getting any money...

Poor them
I say, there need's to be an Event System. Having player's working as Event Team Member's isnt working, and have never worked for year's in the past. Code a system to do Raffle, to do Labyrinth, to do over event's. The system not only would be more effective on giving out item's, it would be random, and it would be more accurate.
Any add on's to Good and Bad reason's?
BTW, Sorry for the Poll Spelled wrong. Trying to get the post up fast didnt help anything...
