I'm a bit surprised at the slow pace of updates, to be honest. I'm sure they pushed to release before the movie and then prepare an update for the movie launch. But then 4 weeks with nothing at all, including no new bundles or even crystal subscriptions, no bug fixes, nothing.. this is surprising. Most mobile games have at least small updates weekly. There were holidays in there, certainly, but again, it has been almost a month.
I too find myself with little to do these days. The forums are more interesting than the game, and that's not a good sign.
I am sure they are hard at work on the next update and if they are spending that time working on bugs and balance issues, then that's great.
I do think the total radio silence on crystal subs is unreasonable, however. We were told flatly that they were only gone because of a temporary issue over the holidays. It's been nearly 2 weeks since then and nothing has appeared and questions about it go unanswered. It may take a long time to balance a whole new update. It does not take a lot of time to put a crystal package in the store.
