Not that I want to get into an argument over this, but have to disagree. The game isn't incomplete, what you get in the box is exactly what FFG want you to have, therefore they have said THIS is the game, the exact contents of the box you buy. The rules don't say "you must have three of each card you include in your deck, but we're only gonna give you some of these, and a few of the others". You can have as many as three of each card, but you aren't REQUIRED to have them, and without them the game is incomplete.
But as I say, this is just my opinion on this matter, and I really don't want to get into any sort of argument about it!
I know it's your opinion. My opening post was also an opinion. I think it's fair to say that everything that's been said in this thread thus far is an opinion, but of course, that's just my opinion.
You don't need to be afraid of having a dissenting opinion. I don't think you are. If you were, you would not have posted it. But don't you think it's unfair to effectively guarantee yourself the last word by saying you don't want to argue about it? That being said, I don't want to argue, either. But I'd like you and those who share your opinion to see where I'm coming from.
Here is why I feel it is incomplete. Core Sets in the past have included cards in 1x or 2x quantities that would be far more desirable if 3x were included out of the box. A good example is the Lord of the Silver Twilight from the CoC Core Set. His text reduces the cost of playing Cthulhu, an effect which is cumulative if a full playset of him is in play. Due to the scaling nature of costs in the game, this makes it possible to bring Cthulhu into play much earlier. But this is an effect that can only occur if multiple Core Sets are purchased, or cards are traded between Core Sets, something that should not be necessary in a game built around fixed cards.
Obviously, such a thing is only bothersome at the competitive level. But I would say that that's what makes the issue of quantity so crucial, from a marketing standpoint. As I understand it, the appeal of the LCG production format is that it evens the playing field, so that victory goes to the player with the greatest skill in deckbuilding, not the one with the bigger bank account. If you don't care about how competitive your deck is, you can buy prebuilt decks for any CCG, at a far cheaper cost than one of the LCG Core Sets. I think that therefore, the extra cost is implicitly associated with the promise of completion in the LCG format. Now that individual packs have adopted a 3x pattern, I simply feel that to fully realize this concept, Core Sets ought to do the same.
I know that's not Gospel, and I don't expect it to be accepted as such. But that's my take on it.
