A Blink-Stalker can't be beat, so you'd think
But when this one heard the call "Zerglings inc!"
It was his nerves I suppose,
When he saw them he froze:
He went blank when he should have went blink
Did you ever think about the Blink ability? Sure, it would be awesome to be able to blink from place to place. Blink across the street, blink upstairs to avoid the elevator, blink through walls for all sorts of interesting reasons...
But what happens if you get confused, or disoriented, or panicked? It's easy enough to get turned around in everyday life, let alone when you are zapping through the ether! And now imagine doing that in a combat situation!
So I figure there must be an extensive Blink Training Program in Protoss boot camp. And it must be pretty funny to watch!
