I'm pretty excited about the expansion and preordered the day the patch came out. I like the card back, although card backs are overrated since it is really your opponent who is the one that sees. It's going to be fun opening all those packs and seeing the new cards. Do you guys expect most play styles to drastically change now? Particularly things like face hunters, control warriors, freeze mages, will classes be playing a lot different that a lot of new learning?
