I'd like to point everyone to the starter post (
http://forum.us.runesofmagic.com/showthr…ll=1#post515545 ) Please go back and re-read what Valentinc had to say, and also note that he mentioned a couple of games which have a truly mixed income model. I've played one of them (LotRO), after it went "Free to Play". I believe it began as a strictly subscription game, and only recently (within the past six months or so) evolved into a mixed subscription/F2P game, with the additional option for players to buy game cards for use in the game store.
LotRO and its stablemate, DDO, offer two subscription levels: Standard and VIP. The differences between the two levels are somewhat minimal, other than the sub prices. VIP allows for more characters per account per server, and more store tokens (Turbine Points) per month than the Standard sub does. Both allow players to reach the current level cap (70 for LotRO, I believe), and access to all of LotRO's content. DDO is or was somewhat different, as even Standard and VIP subs still needed to buy into some of the content. The monthly store tokens take care of that need.
Casual (F2P) players in LotRO can have two characters per account per server, are capped at level 65, and don't have access to all of the game content. They do have the option of buying LotRO game cards, redeeming them, and being able to buy content, extra character slots, or in-game items from the game store. And, of course, they can convert their account to a sub (Standard or VIP) at any time. Sub accounts can also buy the game cards if the player(s) feel they need more game tokens.
One difference I've noted: Absolutely F2P players in LotRO have the ability to gain store tokens and can purchase a permanent mount (using gold, from an NPC, or using the store tokens, if they gain enough of them), along with the needed Riding skill (store item that all characters must have to ride a permanent mount.) There is an associated mount-travel routine that costs nothing but in-game currency, for the most part, but it's off-topic for this post.
Having said all that, I've seen in at least one other thread that it's been suggested RoM migrate to that kind of model. Unfortunately, I don't think it would work very well. The biggest difference in the *gameplay* models is that LotRO does *not* sell permanent power items or skills in their game shop. All "power-ups" are time-limited once you've activated them. Gear modding in LotRO is also very limited in comparison to RoM.
Had the basic income model for RoM never allowed for or offered permanent "power" to be sold in the Item Shop, then perhaps RoM could fairly easily convert to a similar mixed income model (subscriptions + microtransactions.) Instead, Frogster (and we) are stuck with the original microtransaction model. Or, at least, I don't see a way to achieve some sort of "balance", limited as it might be, between sub accounts in RoM and F2P accounts. That sort of situation might actually be worse than the "balance" we have now, based on the amount of "power" that a given player can purchase from the Item Shop. ("Power" can be considered as puris used to add stats to gear, enhancement jewels, runes, and so forth, that are permanently added to gear items, BTW.)
And, to get back to the original topic...I'm opposed to Valentinc's suggestion that diamond buyers be given extra perks or incentives for *being* diamond buyers. They already have more than enough advantages over F2P players, and don't need any more. Better to encourage P2P players to buy their own diamonds every so often, as they can afford to or, as their *parents* can afford to. Keep the latter in mind--we do have a fair number of younger people playing RoM who don't have credit cards, PayPal accounts, or ready access to game cards.
