Here's some feedback...
Don't make the beginning levels of the campaign so impossibly hard. It discourages people from wanting to play. I really would love to like this game but it seems the game ia doing it's best to make me hate it, and it is working.
Lance vs. Eladwen? Frikkin impossible. Lance's deck has no answers whatsoever. And I'm sure as hell not gonna go buy packs or cards with real money if I can't even get past the beginner/tutorial campaign.
Tone down the difficulty so beginning players can feel like they actually have a chance. Because right now it feels impossible to beat.
