Stickies happen, you can't say, 'oh, you got stickied cuz you suck'. There are a million ways to get stickied, and no one is perfect, and neither is backing up. But when you legitimately get away and the sticky still flys half a screen, turns, goes through a house and gets your tank, thats damn annoying. It takes the skill out of the game.
Nope because the animation started while you were still inside the range.
