Game has been playable, with some occasional slow-downs, for several months for me (Linux desktop, FF and Chrome). But the last week or so, something changed. Now it's painfully slow, and almost unplayable. Started about a day or two after the event ended.
I basically only log in 1-2 times a day for the daily reward and collect my arena chests. Even that takes 20 to 30 minutes because it's so excruciatingly slow.
Is this playable for ANYONE now?
