I am not super thrilled forever about this, and have done my share of whining about the whole thing the past couple of days, but I do not see a gigantic issue here.
-I see no reason to believe this is going to seep into "real" Dominion, given Jay's comments on the "Dominion Social" idea.
-There is no reason you HAVE to play Adventure, I don't think. You can get promos from it, but as I understand it you can get promos other ways as well?
-It seems an effective and relatively harmless way to make some money once everybody's bought all the expansions they're going to buy.
-I...am not sure what else everybody expected from a one-player "Adventure Mode" in a multiplayer game that already has the option to have a free match with the AI. I expected as soon as I heard of it that shenanigans of some sort would be afoot.
I dunno, the idea of goofy scenarios actually seems kinda fun to me. As much as I love the game, I am not above a bit of interest in screwing around with variants and such. We can argue over whether it still counts as Dominion or not, we can complain about the nickel and diming, and I will even join you in wishing that the effort that went into it had instead gone into making the game functional, but....I feel that Zaps are not the end of the world.
