Having played with the update a bit, I can safely say I side with the majority here on the flaws that have already been stated. In addition, I have a few points of my own.
One. Aiming melee slams is basically impossible with a controller, because you descend so fast you have almost no time to adjust the stick. So that's another useless feature for us, how lovely.
Two. Some of the channeling issues could be fixed by simply adding an indicator in the HUD to show that you're channeling. Won't get lost in the chaos like the effects and noise. Certainly doesn't solve the autoblock issue, but lets you tell at a glance whether or not it's active, if we're being forced into toggling it.
