Card refunds where you have to exchange the card you paid for to receive an equal amount of dust is free stuff and card changes that drastically alter how you can play a card aren't nerfs. Sure okay pal.
Kaladin, did you choose that name or did Blizzard? We have a regular Theon Greyjoy in here, or should I say, Reek. You are arguing against options for the player base, aka yourself. You need to do some soul searching bud, only the most pathetic of fanboys do a company's bidding without being paid.
You argue for Blizzard's integrity and yet you ignore the fact that not giving refunds for card changes no matter how technical is a new thing that began with Shudderwock. Remember Dreadsteed? That card was changed due to future interactions and had nothing to do with the power level of the card itself but we got a refund. The Yogg nerf is word for word the same as the Tess nerf and we got a refund for that. We even have evidence that Tess' original design was intentional but Blizzard put it under bug fixes. Why is that? How can a design choice suddenly be a bug?
Whether a card is changed fundamentally or technically, the point of refunds is to allow you a chance to change your mind because Blizzard has changed theirs. You want to argue for integrity? How about you show a little bit of your own. All I see is a groveling fanboy who would gladly lick the boots of their master.
