Ahem... Blink was offered by the Warlocks to the Titans, just as it was the with the Hunters. However, the Titans could not use it as the vertical jump intended due to their heavy armor. They were able to modify it, however. If they built up speed, they could "blink" forward with the speed of a jet, and hit like a truck. The Titans can blink, it's just... different. Today, it is known as the Shoulder Charge.
