200ms is faster than the 300ms cast time of Axe's call and Tidehunter's ravage. Pros almost never react fast enough to blink/euls dodge those skills (0s cast time for blink/euls, 200ms reaction time gives the bots a 100ms window to respond). The bots dodged those skills every time. That was the only initiation option available in that draft until late game and the bots were more or less immune to it. That's a pretty significant mechanical advantage.
