Ok, so I have a little input on this... Basically, as much as it doesn't seem there is a problem with Volts right now, it could happen very quickly and steamroll into a major issue. Bare in mind the site is only 2 months old as of open beta, and I joined on the 18th October and already have 85k mounted up.
This means if there are an influx of users, there could potentially be two rather large economic issues very quickly. Number one being the number of volts in the system, and number two being the lack of items to spend Ohms on.
As much as I love that you can equip more than one pose on each crate item, you are essentially opened up to each user only requiring a maximum of 3 of each item. The rares do encourage addition crates to be purchased, but ultimately you can equip all poses for only $15 per month. As much as this is a good figure, many users like to donate in amounts of $50 or so per month, so where do they spend their extra Ohms? They may sell them to other users, receive volts. However, there comes a point where there won't be anything to spend the extra volts on.
Yes, we have commons - And lovely commons, at that. However, the issue here is that not everybody will like every common. Some users may purchase 2 or 3 colors of a particular common item, but then they may never revisit that particular common for other colors. Essentially, the average user may spend 10-20k on commons, as they aren't usually a large part of a user's inventory. At the current rate, you could earn that in less than a week then have no issues keeping up with new release commons and still banking up (rather useless) volts.
As much as a RIG could be a fantastic idea, it also raises issues. If the RIG were to be purchased with Ohms, we need to have sufficient donators to be able to sell the RIGs to users for volts so everybody gets a chance. This then doesn't combat the volt problem, if anything could make it worse as people will attempt to earn more volts to be able to purchase the new RIG items.
If the RIGs were to be sold for Volts, we may hit the snag that lurkers complain they can't earn enough volts for the items, and their only option is to sell Ohms to other users to be able to purchase them. This then brings us back to the market being open enough to sell the Ohms - If nobody wants to spend them on items, why would they buy? Therefore, the price of Ohms could plummet.
So, essentially with this - You could be damned if you do, and damned if you don't.
I also have a bit of an issue with the last suggestion, that would be a LOT of artist work. I understand they could be on 3-6 month rotating rosters, however, the original work to get the item up and running would come at a large cost due to the large amount of items.
The way I see it, is that it could work how Milestone items work. There is an option to purchase the RIG for either Ohms or Volts, and the RIG is circulated out every 2-3 months (Probably 2, to coincide with the rare crate items).
There could be options within the RIG to win;
1 - Rare Crate Item (1% chance)
2 - 1x Unique Ultra-Rare Item (3% chance)
3 - 3x Unique Rare Items (7% chance each)
4 - 5x Unique Common Items (15% chance each)
This way, there are 8 new items, additional shots at getting the rare crate item, and the RIG can be purchased by the majority of users - High posters with volts, donators with Ohms...
Edit: 9 new items. Para can't count. XD
