Yeah critical is now the best since you're guaranteed 5 of them during that burst. The fact that they're also direct hits makes it even better.

However, you'll still want Direct Hit melds to make sure you land as many direct hits outside of Inner Release. That's more of a damage increase than what you would get from extra critical hit melds. But if you're going for critical hit items anyway, you probably won't be able to meld any critical hit into them anyways.

The only problem with the BiS in this patch though is that you will also need to make sure you have enough skill speed to land 5 Fell Cleaves during Inner Release, and how much you get will depend on your ping. I have to stick with about 1500 skill speed to make sure I comfortably hit all 5, which means I'll probably have to end up making some adjustments.
