Sometimes, and this happens quite often, my character would go to trigger an AOE ability for a second time after activating one. This wastes precious seconds and mana in some scenarios, and to make matters worse, the first AOE is cancelled until the second one is triggered.
On other occasions, blocking before a heavy attack with even a full bar of stamina will not actually block the attack, even if the blocking animation is working. I do not know about the first issue, but this one seems to have been one for quite some time now.
There is also a bug on the forums in which I have to select category. These ...categories look like I am choosing where I should place the thread, despite that ebing something that is decided before creating one. Oddly, it won't let me select the Bug Reports section of the forums.
