Okay, first off I am playing this game only for a couple of month and not years, so I don't have that long of an experience with the game.
Manage server like a test server, instead of TRYING to manage it like a finished game. Have the GMs become testing managers, granting ability bonus for testing higher level combinations, such bonuses would only last a month.
Simply: no. Not because I am afraid of the wipe. It's not like PS will be a complete game within 2 years only because of such intense testing. There also is lots of development to be done. I would guess it is important for most people involved, that you can actually play this game somewhat in the many years it is still in development. I also don't think that it would be to the point to grant higher level abilieties only through a GM. This would need a lot more coordination with all the testing players. I guess it IS done with the (real) testers, but to watch a game evolve and to watch chars evolve for a longer time helps the development.
I am not against wipes at all, but I am against scheduled wipes every month. A wipe is only needed when there are serious changes and many things can be planned without an trial and error method every month..
@economy:
In another game I made lots of tables and calculations for the whole economy of the game. That was about 20 different ressources and another 200 completely different "items". For every item you can make or get you have to find out the amount of "gaming ressources" you need to get them (recursively and with some fixed point calculations and so on) and the "value" this item has.
The other game (it was ritterburgwelt.de) was turn based (so gaming time was not a ressource) and the important "gaming ressource" was space, because there was a fixed limit in space for every player. In PS the "gaming ressource" would be the time spent to get and/or produce the Item (PLUS the time spent for the items needed for this item)
The Value would be mainly Tria. This value is related to the items which need this item or at the far end what this item is "worth" to a player (in order to get more ressource through fighting, mining and so on). For some items you need to set a value (a golden ring can't be used, but should be worth some amount of gaming equivalent) And you might have to iterate the model because there are some loops which have to be approximated until they match.
Of course this would also be a constant change as game mechanics and more items get introduced. Even if the game would be complete the prices need to be changed due to changing amount of items being wanted or produced (I an item isn't bought by anybody, the price should go down)
You can do all this in a spread sheet or build your own program with a database with all the recipes an mechanics. It helps to test some things out, but you can develop most of the economy without testing everything InGame. (Still testing that IS important though)
I guess there is somebody in the development who is doing this right? Of course an InGame guild could also do this task and try to enforce some prices, since big parts of the economy are done through players, but it takes a long time to investigate all the game mechanics without knowledge of the exact rules becaus you have to do a lot of testing vor EVERY skill, item and way to produce or get anything.
If this is done, so it must be clearly evident, that some "interesting" parts of the game just don't make any sense because of the way the economy works at the moment.
Like I said, I don't have years of PS experience and don't know any developer personally. This is just based on my experience with the economy in games.
PS:
If somebody is wondering how "professional" my comments are: I DON'T study business (which doesn't help a lot anyways) and I also don't study economies. My major is computer science and my minor is math, so the methods I use are out of that area and the rest is only logic and gaming experience ;-)
PPS:
Training has to be expensive in order that you can constantly train and get better without reaching the maximum in a couple of weeks..
