I'm in favor of this.

If it were to work out like eve it would take about 2-3 full days of play to pay for sub (based on mining in eve).
I would be a person who would fund my play time this way not because I can't afford to pay the sub because I can but because it adds another objective to my play. Alot of people in eve have multiple accounts because dual boxing can be very beneficial but also they like to specialise there characters into particular roles and alot of them fund the extra accounts using plex's. Wether this would come into play in this game depends on how 2.0 turns out.

Being as this system puts a player driven cap on gill value you may see RMT company's switch more into the service side of there bussiness like selling pre-made characters but with increased compitions in those area's those prices will fall as well.

Having played a fair amount of different mmo's and looking at how developers make there revenues you have games like ffxi which rely on subs at one extreme and planet entropia universe at the other with a direct $ to game curreny conversion and everything else is in the middle. For me this system seems the best with one focal item that anyone can choose to use to there advantage if they wish to and there should be no malice towards sellers, buyers or developers in this system if you understand it.

Even if you chose not to buy or sell this item you should benefit from the increase of exchange of currency in the game and better item availability. If you do harbour malice towards this system then you should stop and think about how you can turn it to your advantage unfortunately I wouldn't be able to explain how to do that unless it was implemented.

Now I know some of you are going to be looking at this as the person who is selling game time as being fast tracked into stuff because he is buying curreny but you should also take into consideration that the person he is buying stuff from is benefiting and the person he in turn buy's stuff from is also benefiting and so and so on. Consequently eveyone is being fast tracked not just the person who put his hand in his pocket.

Just to be clear this system does not add currency into the economy but it does speed the economy up increasing the number of transactions completed daily.
