Once upon a time, I created a similar thread, but it remained unresolved. The problem is that when I press and hold the skill key, a micro-interruption occurs, making it impossible to use the channel skills, even though the key is still pressed. Someone might say to check the keyboard, but the issue isn’t with it. I bind key to my mouse, and the same thing happens. There’s a video for clarity, showing the skill icon blinking(https://youtu.be/Z-a79cH4REw). Before, I just let it go and chose a build without channel skills, but this time, I really like the build and don’t want to give it up because of technical issues.
