Oh - yes, completely unplayable. That’s why I keep saying that the addon changes and class changes have to come together. If either of them are messed up, it’s all over.
Feedback on alpha seems to indicate that all classes feel playable, with a few outliers feeling awkward, most notably frost mage. There are also some specs that are being called undercooked, such as fire mage and resto shaman. From what I have seen, I will agree. These two specs got over-pruned.
