Chest Item List

Unless there's some NPC you can buy 60% GFA for 7.5mil from, it is not taking mesos out of the system.

It is bringing more items in, but it is not taking mesos out. The only time mesos are destroyed are when people buy things from NPCS or lose them to taxes. MTS does neither of these. It does take NX out of the system.

I make ~200k mesos/hr, 7.5mil over the duration of the event might be possible (depends how long it runs) but I'm not gonna count on it. Not everyone has an Arch Mage to sell leech for 5mil per hour when they need mesos.

Yes, it's true that different classes have a different amount of income, however, I'm still positive that everyone 3rd job or above can dish out that kind of money by the end of the event.

And yes, it does take mesos out. Here's the cycle in which the mesos follow:

1. Glove Att is purchased for 5mil each. 1% tax is 50K (negilible...)
   
2. Glove Att is put into MTS for around 1K NX. Tax is around 200 NX. (Which is about 1 mil, considering 1K to 5mil ratio.)
   
3. Some Glove Att scrolls are used, taking a direct 5m out of the system, for a total of 6mil out of the system.
   
4. Others are recycled into MTS, until it's used (which we all know eventually will happen.) Each time it is bought and recycled, 1 mil (via NX) will be taken out of the system.

I'll call that the MTS trading cycle, in which eventually, most of the Glove Att scrolls will be replaced with new ones. (either from bosses or from boxes.)
