Hearthpwn

Agree that he's the best minion in the game.  He won't make your deck a hundred times better considering that he's the number one target for silence/removal for your opponent.  However, having him in your deck does help quite a bit and he's 100% recommended for Pally control. 

It should  be pointed out that Kolento is a very technical player and a lot of these cards aren't that easy to use.  The deck itself doesn't seem to rely on its own strengths but rather can counter a variety of different decks if played right. 

I'd keep it just because Harrison is decent.  If it were a Golden Nosdormu or something that you won't use then I'd disenchant it. 

Pretty sure its 500 gold per wing.  About $35 dollars total.  The poster must just not have been looking at the slide right.  Ninety dollars would be too much.   

It's always a real opponent.  That says a lot about the popularity of the game and a good matching system.   

Another thing I'm wondering is how difficult the wings will be to complete.  One would have to think the content would be easy considering that you will have individuals paying money in hopes of getting the new cards with the money spent.  Let's say in order to unlock the cards, you would have to be a level 10 player or better.  That would mean that about half of players (who are higher than level 10) wouldn't be able to unlock the cards after they purchased the content.  Hopefully the content will be challenging enough without preventing individuals from obtaining those cards eventually somehow, but I suppose one isn't guaranteed to get the cards, just the content.               

There is a simple explanation for this:  Only the best players are playing ranked at the beginning of a season.  At the beginning of the season, the player pool temporarily shrinks.  When lower and average ranked players start a match, they end up being matched against the better players, only lose to them, get discouraged and stop playing for the time being.  Therefore there are no lesser ranked players to play against.  Because you are stuck at a worse rank, it feels more frustrating.  It creates the illusion that you’ve become less skilled, but that is not the case.  Once the ranks even out and the lesser players get matched against more comparable opponents, things will go back to normal.
