I'd agree about the "skipping the game" part, if the game had milestone bonuses. Like if you were guaranteed a Legendary card at 5k wins, but I just buy it... yeah... I'm skipping the game. But it's random. Sure there are guidelines to the randomness, but it's still random. I'm seeing dudes on here around 20k picks with zero legendaries. There's no guarantee, and damn... 20k picks for no Legendaries... That's a waste of life (well, strictly speaking, it's kind of a waste of life, even if you picked up 100 legendaries in that same time period). To me, ALL those hours... I'd rather just spend the 20.
EDIT- And yeah... You guys don't feel like supporting the devs at all? You can spend hundreds of hours playing the game they made for you, but you're morally opposed to throwing them a $20?
