Purchases on Ebay are used for 2 reasons.
- Finding something that is exceptionally difficult to get a hold of (due to being out of print, sold out, ect.) and have enough spendable finances to acquire something like it.
- Trying to get something for a lesser price than what it would cost to purchase it from the retailers and distributors.
I would say that most of Ebay business is the latter not the former. Thus judging a value on the secondary (grey)market could be an inaccurate measure of the market. Also it may show that the demand is not as high so such a thing will not be needed.
Netrunner doesn't have that much of a secondary market and that is a card game. Even though the core set doesn't have 3 of each (the maximum number of a card in a deck) you still don't see that much of a deal with Aseops Pawn Shop or San San City Grid on the market. Most people will just buy the 2nd and 3rd core set and use the extra core cards for making multiple decks.
FFG doesn't play by the Wizzards of the Coast market model. The whole purpose behind random boosters is to make ever card sell-able. X-wing does have some random elements but that is in the dice and the occasional flipped up damage card. If you want the thrill of seeing a high rarity tier card coming out of a pack you are playing the wrong game.
