The main situation that this was apparent is Euls on Axe when he blinks onto a target.

Axe's Beserker's Call has a 500ms cast time. Euls is instant. Bots have a 200ms reaction time. Humans have 200-300ms.

The problem is the human doesn't just have to react to Axe blinking on top of them and decide to target him with Euls. Humans also have move their mouse cursor onto the Axe, which for a human is hard to do in 200-300ms (the time they have after reacting to the Axe blink).

A comparable situation that happens a lot is using BKB or Manta to react to a similar initiation. Pros can hit this counterplay much easier because they only have to press a keyboard hotkey, rather than move their mouse to a target first.
