I cannot lie, I forgot it existed for the majority of time. Every now and then I'd pop in, but to be honest, I didn't realize it disappeared to begin with.
All they did was clean up the navigation menu, Dom said they would try and find a new place for the tabs, I don't know if they are fully going to remove it though.
The only time I really used it was when it was first released... after that not so much, I wonder how many people still do use it.
Also, you should have just made a post in the DropBox... a petition in general forums is a little over the top...
I've noticed that you're given a certain amount in the new casino and it doesn't go up as you post like the old casino. So once you're out of CC then you can't play unless it's donated or won. I want my CC back.
