Maybe Blizzard's email got into your spam folder or something. Or, maybe you already have an account from before that's preventing you from creating a new one today with the same email account.
Agreed. Almost every month I think that I'm going to stay with the one I get, and then they release one I like even more.
You need to reach at least Rank 20 in ranked play by the end of the month to be able to receive the card backs. each month is a new card back.
And it's pretty easy, since you don't go down the ladder for losing until you get to level 20. And once you finish a month at 20 or better, you always start at least at 20. So basically grind your way there once and then play ladder once a month and you'll always get the new card back.
I've found a really fun synergy. I play Kel Thuzad behind a taunt and then Faceless the Kel. What's amusing about it is that it's an instant concede from your opponent, almost 100% of the time. If they don't concede then you just TRY to kill your minions on his and hit the face after his board is empty. I'm using this on Ramp Druid. Unfortunately my win/loss is about 50/50. But it's really fun, and it's good for clearing Druid quests. I haven't tried this on any other classes yet.
I wouldn't like to play HS on an iphone! I think my mini ipad is about as small as I'd like to play it. And unfortunately, it's been awful on ipad thus far. Constant crashes, lag, freeze ups ... on a solid connection. Many people are experiencing same. I just stick to playing it on the PC, and even on there you experience random crashes, but at least the reconnect feature actually works now and then. The recent card back is the nicest one yet. 'Icecrown' - I think the Pirate one will be just a novelty, like the rainbow one was.
One look about on forums suggests it's happening to Ipad 2, 3, 4 and mini. It really should not be only optimized for the newer versions. No other games have this issue, I can throw pretty much any new game at my mini and it'll run without any hassle. I play HS on laptop mostly, and it happens on there too. Just not as much. [edit] - Looking at threads on reddit on the issue, many ipad air users have experienced crashing too. So it is not just the older ipad mini [which is basically the same as an ipad 2]
