I think this is one of the best card games you can get, the dice makes each card "imperfect", so unlike Magic or Keyforge where you can look at your hand and spot the best play with Destiny you more often than not have to take what you get. This makes the game far more enjoyable as a "puzzle" every turn you have something new to solve with the cards and dice you have.
Sadly though the game is hard to grow, new players are cherished, and I think we sometimes are so excited to have new players that we are so nice we scare them off.
Many play groups seem to be hitting the 4-6 player mark and I think this puts pressure on those players. The play group being so small means you are playing the same people over and over with the same decks. Then the cost of the new sets just adds to this pressure because you aren't getting value for the money your spending. It only takes one player from a small group to quit and the whole group reaches that tipping point. In some regards if you are here reading this you have out done at least one other group that has given up, if not more.
But I don't think it is the games fault, it is the sales model, we don't have enough players to support a blind buy. Singles are becoming harder to find and that too is making the CCG model harder to interest players. I just don't think we can do this for much longer. Mind you I think the idea of an LCG is also problematic because that to drives away players over time and creates a barrier to entry. The game evolves far too slowly and if you start late you still have a huge cost to catch up. Overall I think both the CCG and LCG model will slowly strangle this game.
I would look at making the next set the last of the blind buys and moving forwards produce box sets that have one of each card. Alternatively make a box of 2 of each non-dice card and a box of 2 of each dice card, that would allow people to buy 4 copies of the non-dice cards and make more decks where the cards overlap in their decks. Not only would this make the game more friendly to players, it will also make the production easier for FFG and the distribution easier. I went to the Sydney GQ and any drafts that were run saw a table full of common and rare cards left on the table, those useless cards still have to be made and distributed by FFG, so cutting down on the waste cuts down on their end of the supply problems.
I would truly enjoy myself playing this game in 5 years time, but I honestly think something has to give to make it have a chance.
