I remember when I was joining the site. The reason was at first just to have a place to keep all of my silly decks. But I always enjoyed the other aspects and even though I didn't participate that much I will miss it. With things like the "Real Casual Play Network" I made a lot of new friends.
This change couldn't have come at a more fitting time for me. With the Dalaran Heist the Solo Content now offers so much new and exciting ways to play that the Multiplayer now just pales in comparison. I will probably keep at it a little with the monthly card back and occasionally a fun meme gimmick duel with a friend if I get the 80 gold quest, but otherwise the Singleplayer now has the awesomeness I always wanted. Sure, some things could be improved, but overall it's interesting, but also sad to say that I probably won't even miss the community aspect.
So at last thanks to everyone that participated here. It was a great time and this will be a big change for many. Let's see what the future brings.
