So why hasn't Goko made the other three purchasable? This is really getting frustrating. If they made all the promos purchasable with Gokoins, or if they provided away to earn 500 VP, or if they had launched Black Market and Stash as purchasable with Gokoins... any of those would be acceptable. But right now, they've probably just pissed off customers who spent VP on Black Market and Stash during the past week, and are now for some inexplicable reason among the few users who cannot attain all of the promos. And there is simply no rational explanation for this that I can think of.
I can see good intentions in Goko's original plan. I appreciate that they were allowing us to obtain the promo cards for "free" rather than selling them. I also appreciate that they intended the promo cards as awards at the end of a fun and unique adventure mode. But the adventure mode was not fun. They totally screwed the pooch on that one. But there are other fun ways of giving out VP. I feel that what most of us want is a fun way to earn promos while playing against other humans. Why not implement an achievement system, like the one CouncilRoom added to Iso, and award some number of VP each time a player unlocks an achievement (for the first time)? So long as most of the achievements are fun, we'd even let slide a few money grubbing ones, like "buy an expansion", "buy all expansions", "play a game every day for a month", and so on.
