In a real economy, adding more wealth (even if it's precious metals) should not increase inflation, since inflation is caused by increasing the representations of the wealth instead of the wealth. War and disasters would decrease the general wealth, and thus the value of money (even though tria are not notes of commerce, and thus aren't even representations), while fruitful labor would increase the general wealth and value of money.
I see Plane Shift economy (Yliakum settings economy would act normal, kinda) doesn't work that way, but exactly why is it so? (Rhetori▬) From the bugs and suggestions I've seen on the tracker, and conversations here, it doesn't look like the economy conserves anything. Wealth comes into existence and ceases to exist upon the guided and controlled whims of the players, using a number of production sources and sinks. Tria acts just like printed notes would, because they are of infinite source (like a government immediately minting notes in response to any wealth created) from traders who (quickly|instantly) eradicate the goods.
So the inflation exists because for any wealth created, more tria are ~minted to represent that decreased wealth. The players doing it more will make it worse, but as long as it's designed that way it will be a problem. (Or the reverse, where there are too many sinks and people run out of the inflated money.[sarc] Or worse, complain that they aren't rich enough![/sarc])
Along with conservation, it would be good for the economy to care about a system of supply and demand; including all it implies.
Yeah, but the consequence to making leveling easier is that people wont get to use their levels to be elitist (a...bad thing?), and those non-role-play newbs will be more likely to attempt "lording over" others with their perceived power. A direct method will make it suddenly feel like the level caps are far too low.
I don't know whether it would be a good thing or not. Can you think of any MMO that hasn't relied on hard leveling as part of its foundation?
Edit: Oh, and I'm doing it again; almost 18 hours now.
