This is something that I notice has been happening more and more often and I wanted to see if anyone else is experiencing this as well. At times when trying to use skills my character will start the skill animation but it will stop half way through. This happens no matter what skills I try to cast and even my normal and heavy attacks can't be used either. The only thing that seems to break my character out of this is if I smash multiple buttons on the PS4 controller at the same time and eventually my skills and attacks will start working normally again.
