This has been a newer issue for me since the July 18th patch.
When I press my ultimate skill keybind the Sound AND Visuals will trigger exactly as it does when [truly] activated but often, more than often actually, it does not actually activate the Skill.
The sound is there. The initial effects for when the skill is initiated is present but when i look at the Skill Icon on the hotbar it is still “ready to be activated” and is not doing anything–the effects fade away too. From here I can press it a 2nd time and it does, always, actually activate.
It’s the Unstable Current ultimate for Sorcerer by the way.
I tried changing the hotkey to something else but it persists to have the problem (obviously, since the sound and graphics DO actually initiate on the keypress; so it DOES recognize I pressed the hotkey associated with the Skill).
ONLY the ultimate skill. Everything else works fine. I press the Teleport hotkey, always works, I press the Frost Armor hotkey, always applies the armor, etc. It’s JUST the Ultimate Skill.
My current workaround now is to mash the living F out of that key when I need it. lol
